That's pretty much it in a nutshell, though I know I missed a few here and there, lol. Never seen any Hentai really
I try to switch it up and watch as wide a variety of Anime as possible, and for the most part everything I've seen I've very much enjoyed. There have been a couple exceptions however, lol.
FILMS/SERIES *NOT* TO WATCH
The Weathering Continent (complete lack of storyline/plot, no character development, animation not consistent, etc.), Brain-Powered (pretty much same inconsistencies as TWC, ugh)
