I thought it was decent. Started well enough but I found the last couple of episodes to be a bit of a letdown. In general I think these (Netflix) Marvel shows tend to hit a ceiling of how good they can be.
The one exception I can think of is FX' "Legion" (which was allowed to be wonderfully weird) and even that was somewhat taken down a peg when they were forced to become slightly more conventional for the season finale.
As for the attraction level, Frank is alright but I prefer Curtis.
