The shows alright, but not intelligent. The show used to be somewhat aware of this. It used to be a common gag that Rick got shut down when he went on his self-indulgant rants about how smart he is.
I always liked to think of it as Dan Harmon being himself until the actual writers got their hand on the script.
Season 3 didn't really do that, though. It made Rick the hero even though he's obviously an asshole. The worst was when he was telling Beth about how intelligence was a curse. It was hard to watch, it felt like the writers were pandering to the stereotypical "intellectuals" who think the show is the height of academic wit.
