I know alot of People don't like Gonzo(Anime Studio). But I was wondering why? they've made so many good Animes, what's there to hate?

They either have good animation and but bad storyline, or vice versa. Compare them with Key, they suck, but with many other 3rd rate studios, they're pretty decent.

I think you mean Kyoani, as Key is a visual novel company.

I'm not too familiar with the company overall, but it seems they simply don't stick out with entertainment or depth, nor have any flagship anime to boost their popularity with. Saki may be turning this around though.

Another criticism I've heard regarding Gonzo is that some of their works are tailored towards the western audiences, which would naturally lower their popularity with the native viewers.

Yuh Kyoani, mixed up @.@~

And Saki sucks storyline wise... other sports anime explain the rules as they go, Saki doesn't, full of fan service, and the occasional major error or rules which the main character should not of won.
