Edits will be done in bold.
One day, the world decided what we really need is another "Battle Royale" rip-off.
Story: Sakamoto Ryouta is good at an online game called BTOOOM! Actually, he's very good. Actually, he's superb. Actually, he is so good he is unable to recognize a TIME BOMB. The antisocial guy finds himself on an island, where he discovers a few supplies and nothing else. He is confused, but drinks all of his tea because it apparently makes you less confused. He looks at his hand, sees a gemstone, and realizes this is like BTOOOM!. He looks in his pouch and finds little cubes. Apparently, awesome BTOOOM! guy is pretty stupid, because he doesn't recognize it. I immediately knew it it was a bomb. He clicks a button and it counts down. I then knew it was a time bomb. Artemis Fowl here can't figure out what it is. He has a suspicion that the numbers mean something, so he throws it and it explodes.
YOU THINK IT'S A BOMB NOW, DUMBASS?
He is attacked by another guy with bombs which explode on impact. Not only does every single bomb dodge him (yes, the bombs dodge him. He sure as hell can't dodge the bombs), but one explodes in the air. Apparently, "explodes on impact" can refer to molecules. The other guy must be a really crappy BTOOOM! player if he can't use a bomb to kill a boy who's ten feet away. Ryouta takes a gamble and jumps into the sea. The other guy is waiting for him to surface when one of Ryouta's time bombs goes off from under the guy's foot. Screw the fact that the time bombs make noise!
Ryouta is relieved. And the moron survives to see another day!
We then switch perspectives to see the story of another BTOOOM! player, a little bitch by the name of Himiko, which is apparently Japanese for "f*ck me, please!" because this girl is a whore. She cowardly allowed her friends to get raped before the island, but now get's stuck with two older men. (Really smart. Seriously though, how stupid can you get? They could be nice, sure, but you might not want to risk it, especially if you're a pretty girl with a large chest who almost got raped before. LEARN FROM YOUR MISTAKES!) This just ends up with a man trying to rape her. She lays there until she remembers her bombs and tries to commit suicide and homicide, but the rapist runs away and she hits only him. She then thinks that all men are scum (didn't think of that before, didja? /:) and starts to wash herself in a waterfall. Ryouta sees her and she runs away. But if she and him get together and whatnot, I TOTALLY CALLED IT AND EVERYONE SHOULD HAVE BEEN ABLE TO SEE IT COMING FROM A MILE AWAY!
There's episodes one and two in a nutshell.
Am I supposed to BELIEVE this? The guy who is awesome at BTOOOM! can't recognize a BOMB, and a girl who almost got raped before can place enough trust in a man to allow him to lead her anywhere?
Later on we learn of how the people on the island got there. A happy-go-lucky man on a TV told them everything and blah blah blah. Long story short: It is a BLATANT rip-off of "Battle Royale."
But these plot holes play second fiddle to the really problem of this anime: BTOOOM! is one of the stupidest names I've ever heard. Another one: The dialogue is beyond cheesy! This is especially evident in episode six, which has some of the corniest speeches I have heard. Plus, our main cast (well, mostly Sakamoto, then Taira, then Himiko) seems to think that everyone is out to backstab them, even within their group! How many times has Sakamoto said, "TAIRA-SAN JUST LEFT US HERE TO DIE! Damn, I should have known--hey! Taira-san, ol' pal, where were you? Nice to see you again, ol' chap!"? Seriously, is someone keeping count?
Yet another one: DEUS EX MACHINA. Or, in simpler terms, PLOT DEVICE. This anime is so full of plot devices (especially episode nine) that it is almost insulting. Do people think that no one will notice these? That an unconscious girl could throw, in one second, a bomb far enough away from her to not even harm her (and she's in a forest, no less)? That a boy can have a bomb explode under his feet and remain unscathed? Et cetera, et cetera, et cetera? There is also some diablous ex machina, especially in episode 10 or 11.
Oh, yeah, and the ending is awful. I won't spoil anything, but it is bad. Really, terribly bad.
Animation: I've seen better and I've seen worse. Compared to the other Fall 2012 anime I am watching, it's pretty sad. Character designs are lackluster, from Ryouta's Yagami Light impressions to Himiko's blonde hair and big chest. Backgrounds fare a bit better, but are still rather nondescript. The explosions look cool, but everything else is only a step above average.
Also, this anime goes out of its way to include fanservice. A bomb bounces off of Himiko's moonbounce of a breast. Himiko's panties are pink, if you care. In addition, I have never understood why an anime girl blushes when a guy sees her naked after she runs out of the shower. Of course, that scene happens here, with Himiko (and her stupidity) emerge from a shower, only to have her... yeah... be censored by a well-placed leaf.
Sound: The OP isn't as bad as I make it out to be (it might be the best part of the anime). However, this point still stands: The OP is forgettable and so is the ED. Insert music is mediocre. The voice acting is on par with many other series. I cannot applaud it, but it serves its purpose. No voice actor in particular stands out as exceptionally good.
Characters: Development may improve as the series progresses. No.
Main characters: Boy with blue vest: Kira Kosuke, old man: Taira Kiyoshi, girl with blonde hair: Himiko, man with short hair and glasses: Date Masahito, man with long hair and sunglasses: Oda Nobutaka, boy who looks an awful lot like Yagami Light: Sakamoto Ryouta.
Sakamoto Ryouta: The guy who's "really good" at BTOOOM!, as he tells us every fifteen seconds. I would be better suited to the survival game, and that is saying A LOT. He's a love-him-or-hate-him kind of character, and he'll hopefully become more likable. Well, he doesn't become more likable, all he does is become more and more naive. Eventually, this makes him into a hypocrite.
Himiko: Unfortunately, this is not "GANTZ" and a sexy female character probably will not be killed off. (Minor spoiler for "GANTZ?" A bunch of minor spoilers?) I hope she dies. I've never liked the damsel-in-distress role. (And her fanservice role sure isn't helping.) Her backstory is just too unbelievable to be tragic; I know rape is a horrid and prominent part of many people's lives, but her past seems forced.
Taira Kiyoshi: He is, in a nutshell, pointless. As far as athletic ability goes, he is by far the weakest character of the bunch. It would have been a good idea to have given him psychological balance instead (or make him go crazy, that would have been interesting!), but he is simply a spineless old man, relying on Ryouta to save him multiple times. It is also hinted at that he will abandon the gang (actually, it is much more obvious than just "hinted at"), so all credibility for anything he does is lost.
Date Masahito: He brings the word "asshole" to new lows. He is manipulative and selfish, and couldn't care less about the people he says he loves/wants to protect. Unfortunately, a large amount of plot devices, a lack of logic and a whole lot of moronic characters surround him. Overall, not a good villain.
Oda Nobutaka: Poorly fleshed-out character. I can't describe him.
Kosuke Kira: He's a 14-year-old boy who raped and killed three women... and he has a sexually and physically abusive father... and he is crazy...
Murasaki Shiki: She has a backstory stolen straight from "Battle Royale," and she really doesn't do anything worth mentioning.
Overall: Hopefully, this series will improve. I give up. Don't bother watching this series.
