People who dislike anime, what made you hate anime?

Most people who hate anime haven't watched any themselves and hate it for the stereotypical reasons, like how its supposedly too sexual or too childish or the fanbase is too annoying. Normal people either don't care or think its cool, people who hate it are usually just looking for things to hate. 

I don't "hate it" per se (otherwise, why would I peruse this section from time to time?) but I will say I don't see how some of the more popular series have gained the popularity that they have. I was big time into anime "before it was cool" - when there was attention to detail you just couldn't find in other methods of animation, when the stories weren't overly filled with padding or fluff episodes, and when the action was fast-paced. I've caught some series on "Adult Swim" fairly recently where instead of actual animation, the bulk of the episode was comprised of stills using the Ken Burns effect with an internal monolog voice-over - there was maybe 15 minutes of actual animation!

Otherwise, you have series such as Dragonball that are supposed to be centered around fighting where they gab at one another for 21.5 minutes of an episode (again, with stills and monolog), then have about 30-seconds worth of actual fighting, only for the action to be interrupted to end the episode "...join us again next time to find out, on Dragonball!". There's also Jojo's Bizarre Adventure which has effeminate-looking "macho men" with super-secret powers only revealed at the last possible second of what should be their demise. In fact, a lot of the more recent anime I've seen has an over-abundance of deus ex machina.

The best recent series that I've seen would probably be "One Punch Man" because, while story-driven and following an overall story arc, the action is frequent, fluid, and exciting. That was a shining beacon of light to me, though, and it's supposed to be a parody.

Overall, I don't HATE anime - I just don't find it to be the quality it used to be overall, but to judge ALL anime as such is unjust, as it is pretty varied throughout. It's like asking "why do people hate movies?" or "why do people hate food?"; you're painting with a pretty broad brush.
