It went like this to me;

-season 1: nerdy, dnd, 80's, cool little corny/campy coming off age story.

-season 2: nerdy, 80's, cool little corny/campy coming off age story.

-season 3: cool little corny/campy coming off age story.

Season 4: the only thing remotely first season was the name of the club.

The big bads are loosely DND influenced and in name only. I rewatched the first two seasons a few times. But I got all I wanted out of the previous two on the first watch. And I'm not saying they're bad, they're just losing me. At least Jack Black isn't in it I guess.
