I am going through the DC TV series, so I'm juggling Arrow (which is great up to season four where the quality of the writing just goes to hell), the Flash (which is all over the place), Legends of Tomorrow (which seems to be made up of rejects from the previous two shows, although I like Sarah) and Supergirl (which is AMAZING) right now.
I'm also watching Star Trek: Enterprise on Netflix, which isn't as bad as Deep Space Nine - I can't believe I forced myself to sit through all of that - but it's not even remotely close to The Next Generation or Voyager in terms of quality. Every time I see Trip I think of Michael from Stargate Atlantis too, so I keep expecting him to murder somebody...it's very disconcerting. Especially with that accent he puts on...
