The first season was the best season so far. I loved the first episodes because they were freakin hilarious. Now i just watch hoping for at least one good joke, but i am disappointed almost every episode. Most of the jokes now just seem like quick half-assed ideas thought up 5 min before making the episode.
Also, Rob(the writer) is getting a bit of an ego problem. Insulting viewers(some do deserve it) and not putting any effort into writing a good episode. I would rather wait forever and see one good episode, than watch many bad ones in that same time period.
