I'm currently steaming through
Star Trek TNG Season 3 and apart from a few bum episodes it's been great fun so far, really looking forward to the end of the season and the excellent
Best of Both Worlds episode.
I've also just started watching
Nashville season one on NowTV, not exactly cult TV but it does have a star from
Heroes and one from
American Horror Story 
I have to say I'm enjoying it a lot, it's not high drama - it is just literally fluff to keep you entertained but the music is great fun and the look and feel of the show is good as well.
