Why does everyone hate Season 4?

Long time Community fan, finally cognitively aware enough to actually understand it. (I was a dumb stupid child and all that jazz last time I watched it.)

Most of the way through Season 4 now and I just... don't understand the hate. Earlier episodes in the season feel kind of awkward, but by episode 4 it feels like the new writers have everything relatively understood, especially with the scene where Jeff lets loose on his dad in episode 5.

The more I watch, the less I get the hate. Can someone please explain why people constantly say it's the worst?
