One such gimmicky sitcom is The Good Place. The authors did too good a job of making the main character insufferable in the double-length pilot episode, however the episodes have been continually improving. The authors aren't super-creative. For one thing, their jokes about what makes someone a good person, such as not sharing about veganism unsolicited and not claiming to identify with reality TV stars--feel like they're trying to hard.
For another thing
Any rate, for some reason, despite the uninspired writing I'm still finding myself enjoy the show. Maybe it's because of the excellent acting, maybe it's because of the excellent sets. (I'm not embarrassed to admit that I watched every single episode of Two and a Half Men because I found Charlie Sheen's fake house almost erotically appealing to look at.)
The one thing that annoys me about it though: Every fucking episode ends on a cliffhanger. That reeks of desperation, and if the series lasts more than 18 episodes (I think it's not unlikely NBC will order five more episodes for lack of anything they're confident will do better in its slot) I will be amazed.
