I just watched Troll Hunter. For being a subbed, foreign, found footage film, it was quite enjoyable. The CGI was pretty good.
Stargate Atlantis/Universe are both good too. Atlantis is more comical, while Universe is more gritty.
Battlestar Galactica is not bad either, although it's a bit heavy to watch at times. I can't really watch more than 2 episodes in a row.
From Dusk Till Dawn (TV Series) is a pretty good reimagining of the movie.
