I'm just a guy from Canada (now in Texas) who likes to watch anime. For all the anime that I watch now, I only got into it a few years ago, actually. I had a friend growing up who watched, so I was sort of exposed to it back then with Ghost in the Shell: Stand Alone Complex and InuYasha airing on YTV's Bionix block, but I kind of avoided it when he was watching.
Then, during freshman year at university, I started watching Naruto for reasons that I still don't understand. That opened the door to Fullmetal Alchemist, which lead to Angel Beats!, which lead to Clannad, and I was hooked.
On that topic, my favourite anime of all time is hands down Clannad: ~After Story~. I'm a sucker for romances and tear-jerkers, so I love Key's work. Jun Maeda, specifically. That man has too much talent though. He shouldn't be allowed to be good at writing stories that make me cry AND an amazing composer of music. It's not fair!
Just to give you an idea of my preferences, my favourite show of all time (not just anime) is Avatar: The Last Airbender. The amazing story that stretches across three seasons of well planned, brilliently constructed, cleverly written, objectionable-content-free children's show is simply fantastic! I just cant' get over it! This is the show that I've seen the most, out of any show, ever. I've lost exact count, but it's over 10 times now for all 61 episodes. Watching it with me is a requirement for any roommates. As for live action shows, my favourite is probably Awake, the canceled show from NBC. It was good while it lasted.
My ratings break down like this:
1.5 stars: No. Just... no.
2.5 stars: Low. I did not enjoy this.
3.0 stars: Fine. I can see why people would watch this, but it's not for me.
3.5 stars: Good. I enjoyed this show, but not enough to rewatch.
4.0 stars: Great. I would rewatch this by choice, and may reccomend it.
4.5 stars: Fantastic. I actively rewatch this with other people.
5.0 stars: Simply amazing. I will buy this show one day, if only to support the production team.
The star ratings are just general ideas of my opinions of shows. Any specific details and precise scores will be done in an actual review of the show. 5 stars does not mean that the show is perfect or would recieve a 10/10 in a formal review. It simply means that I really liked it and want to buy it, and everyone else should watch it too. Also note that lower than 5 stars does not necessarily mean that I don't want to buy it. Truthfully, most shows 4 stars and up I would be happy to own; it's just that any 5 star shows made me feel that not buying them was not an option becuase of how they impacted me.
For some reason, I like to know about what studios produce what shows, and why, and how the logistics of it all works, so I've noticed that I really like Kyoto Animation. Not just for their work with Key (Clannad!), but also for Nichijou and Tamako Love Story and the like. And, possibly more importantly, they have an awesome buisness model and treat their staff well.
One thing that I can't stand is any Ecchi content. I'll put up with a tiny bit of fanservice, but if it gets too extreme, I'll drop the show. I can deal with some language or violence, but I have been known to drop shows that have too much of that as well.
As far as dub vs. sub goes, I don't really care that much. Typically, if given the choice, I'll take a good dub over a great sub, just because I find I can get more immersed in the show if my eyes aren't constantly glued to the bottom of the screen. It makes it a lot easier to catch the subtleties of character animation. If the script is localized, that's even better. Subs should be more literal than dubs in general.
I've recently gotten into manga (blame Crunchyroll) and light novels (blame J-Novel Club), though I do still prefer colour, sound, and motion when I enjoy a story. I know that many anime are designed to get people to buy the manga, but I've honestly found the opposite to be more true for me: reading a good manga makes me want to watch the anime version (looking at you, Yamada-kun).
Now, if you'll excuse me, I have to go rewatch Avatar again... The tv show, not James Cameron's Avatar. Sheesh. Why does nobody get that? Seriously!
