Hey there, I'm one of the OLD (I'm in my 30s now, I get to emphasize) reviewers for AP, back when we were staff-written. I still check in from time to time, and recently started throwing reviews up on occasion as I slowly work my way through an 8 year backlog of series.
MY REVIEW SCORING CRITERIA:
Numbers divinated from the arbitrary and convoluted book of review scoring:
<5: Stay away. They employ little but cliches, recycle already-done material, and fail at having a coherent story and relatable characters. Perhaps some fringe appeal to those who like just about anything in a particular genre, but they're just different shades of terrible once they get down into this range.
5: Average-but-Mediocre. These shows again are probably worth watching only on genre appeal, but they're at least entertaining at times. There's better things to watch given their mediocre presentation on all fronts, but if you're exceptionally bored they may prove an apt way to rot away both the hours and your brain.
6: Average-but-Passing. These series are neither particularly good or bad, but are definitely watchable. They do some things well, others terrible, but they manage to attach some unique flavor or appeal to their story and/or characters.
7: Good. These series generally keep my interest throughout by means of a coherent and interesting story and a compliment of characters who have some semblance of depth. They provide for an overall enjoyable and entertaining watch, and generally define genre-norms and set the minimum bar for a "quality" series.
8: Fantastic. These series are the vanguard of good anime. Their stories develop a sense of intrigue and the characters are fleshed out with both depth and flair. Every series that hits this rank has the ability to define its material as unique and is compiled in an intelligent, thoughtful manner designed to captivate the viewer.
9: Top of the line. Perhaps the only major distinguishing factor between an 8 and a 9 is my personal level of interest, but they're undoubtedly the cream of the crop. They are defined by remarkable execution in every area and generally operate on a very unique mechanism to push their story forward (the remarkable world building of Twelve Kingdoms, or the ability to play flawlessly on the suspense of weekly releases like Death Note). Certainly not to be missed.
10: None yet!
Some people have also asked me why I use decimals for overall - I use them to indicate a leaning. Generally if I feel an anime is, say, between a 6.5 and a 7.0, I'll show that it's a 6.5 leaning toward a 7.0 by using a score like 6.7.
NEW REVIEWS SINCE MY RETURN:
Parasyte - 1/30/20 - Very nice horror/drama. Not as gripping as Shiki, but still quite solid.
Deadman Wonderland - 1/20/20 - Get rekt, Fate/Stay Night has been upheaved as awful shounen champion.
Shiki - 1/16/20 - Blew me away. Spectacular dark drama without cucked vampires.
Mahou Tsukai no Yome - 1/13/20 - A disappointing attempt at a mishmash of genres that was too timid to ever go "dark."
Orange - 8/18/19 - What AnoHana should have been if it didn't suck, but still "okay."
Your Lie in April - 8/6/19 - Another top tier series. Elegant, beautiful, and definitely should be on your list.
AnoHana - 8/4/19 - So very disappointing...
Wotakoi - 7/30/19 - What an absolutely fantastic slice-of-life comedy/romance.
Violet Evergarden - 7/28/19 - Aesthetically absolutely gorgeous, but riddled with holes.
Grimgar ~Of Mediocrity and Meh~ - 7/27/19 - Average and bland with enormous unused potential.
Just Because - 7/21/19 - Bam, four! With a fifth to follow soon (this next one not so nice.)
Our Love is Only 10 Centimeters Apart - 7/19/2019 - On a role here, knocking out another romance anime. Check it out!
Golden Time - 4/22/2019 - And another? What is happening?
Youjo Senki - 2/24/2019 - What on earth, a new review after like 7 years?!?!
