How is Key জীবন্ত seen in the জীবন্ত community?

I've just started watching জীবন্ত this বছর and I've been watching ones that are pretty well known, and that reasonably short (less than 2 seasons).

Some of the জীবন্ত I really enjoyed were Key Animes including Air, Kanon, Clannad (and After Story), অ্যাঞ্জেল Beats and Little Busters.

Some I'm curious to how Key জীবন্ত is viewed in the জীবন্ত world.

For example, is it seen as:
Too mainstream?
Too emotional?
Awful?
Really good?

Like I've ব্যক্ত I'm new to জীবন্ত and I'm just curious what well rounded and veteran জীবন্ত অনুরাগী think of Key. BE HONEST !
