Anime, just generally anime, most anime i cannot stand because different aspects of separate shows act so similar to each other.
so many scenes and mannerisms play out exactly the same...too many to point out.
pretty much Egoraptors "girlchan in paradise" shows exactly what i hate about anime, even though it is COMPLETELY dramatized to a significant degree, it sums up everything.
although this doesn't mean i do not appreciate certain anime. i can appreciate (but wont watch on my own) animes like trigun, hellsing, ghost in the shell, cowboy bebop, death note, neon genesis, and many others.
the ONLY anime i fully respect and love to watch is Full Metal Alchemist (i prefer brotherhood). although it has a few of those quirks and mannerisms of anime that i usually dislike, FMA does them RIGHT by having my kind of humor, as well as the characters actually acting developed. It also avoids having unnecessary gimmicks (impractical bits of clothing and what not) as well as it avoids the all too common sexual innuendos that you see so often in anime (it only really does this with lust, but with her it actually makes sense).
