It's kind of odd right now that I'm actually watching something like 4 series:
1) House: yes, I know I'm kind of tired of always about the same thing over and over again, but it's entertaining sometimes.
2) Fringe: a brand new series with 4 episodes so far, maybe 5. It's kind of an X-Files with a little more emphasis on technology and less on aliens or the government trying to hide things from us. I've been quite happy with the results so far
3) Terminator: Sarah Connors Chronicle: Ok, this one I'm a little embarrassed to say that I've been watching. It's really not a good series, but I think it's a little bit of being old and remembering watching the movies.
4) True Blood: I'm not sure yet if I like this series. The acting is pretty bad, but there are some interesting oddities to it. If I fast-forward through all those sex scenes, it has been watchable. But it's in the fringe of derailing to "vampires are evil and let's kill them all" type of thing. If it does, I guess it's going to come out of my list.
I'm waiting for another couple of episodes of "Knight Rider" to really consider this series trash. There is also a new potentially ok SciFi channel series starting this Friday, Sanctuary. It looks trashy, but, well, I'll have to find some time to have a look. One good think about most of those series is that they only have new episodes every other week, so it allows me to have time to watch them spread out through a couple of weeks. The beauty of a DVR and Hulu.
