@art style: Yes, it turns me off if I do not like the art. Like one piece.
I also get turned off when the "bida" is a kid. Though if I like the story and the art I would reconsider. One example is Naruto. At first I didn't want to watch it because I hate kids na bida but when I watched a few episodes and liked the story ni watch na ko padayon.
I also hate fillers like sa naruto and bleach.
Also sobra ka taas na anime eventually bores me and I just stop watching.
I prefer only 20 plus to 50 episodes.
Of course the story. If di nako type then I won't watch it.
