No character growth, characters who are shitty and shallow, no central plot point - these are all very intentional themes. It's a dark comedy and one of the central features is all the different flavors of shitty each character is. Let me guess - you also hated Seinfeld because the characters were awful and showed no growth over nine seasons.

There's a difference between a show being terrible and you simply just not liking it. I'm not a fan of ballets, but I'd be quite a dipshit if I complained about a critically acclaimed production and whined about the lack of dialogue. Get a clue, OP.
