I used to think Danny DeVito was something of a square peg on the show, but I've come to like his character as much as anyone else's. I kinda think the first season is the best when ranked on certain criteria (ie. it is the least overtly wacky season), and I think I kinda blamed DeVito for that "era" going away. Now, I really don't care anymore because the show is still generally fucking hilarious.
