What I have been wathing:
CSI: I'm not sure why I bother. I haven't seen the latest one yet (aka this week's), but last weeks was so bad, I'm not sure I even want to see it.
WaT: Two good episodes in a row! Plus the x-over earlier this season. This might shape up not to be too bad after all. I'm optimistic for a change.
Criminal Minds: Love it this season. Plain and simple. Love the new guy. In the past it was never really bad nor really good, but it seems to be one of those shows that get better over time.
Cold Case: I wasn't thrilled so far but the cases this season and didn't manage to finish this weeks' episode.
LaO: I miss the original series! I was unable to finish either of the most recent episodes (at least I think they were the most recent ones).
The Sentinel: It's one of those shows I've been meaning to watch for years (mainly because of the fanfic I've read), but I was sorely disappointed by what I saw. It seemed cheap and unimginativ. I don't mind the cheap bit, otherwise I'd never watch old!skool DW. Some of the fanfic really is better than the show itself.
NCIS: Also from the catch-up list. I'm having a hard time forming an opinion about that show. It's not bad, but I wouldn't call it first rate television either. It's pleasant watching, for the most part. I did like the Halloween episode. A lot.
CSI-NY: The only CSI that is still good. Period.
CSI-Miami: I've stopped watching. And I already missed most of the last season. I did like the episode where Speedle showed up. But it seemed like a very odd episode for CSI. Maybe that was why I liked it.
Numb3rs: Haven't seen the most recent episode - 4x09 I think it was. But so far the season has been fairly average. I still miss Terry. (Anyone remember her?)
What I haven't been watching:
SGA: I still haven't forgiven them for the S2 (that's right - S2) finale. It's bad sign when there's a cliffie and I don't want to know what happens next. Plus the Ford-thing. That was badly handled as well.
Supernatural: Equally disappointed by the S2 finale. Not quite as bad as the SGA one, since that actually made me angry.
What I still have to catch up on:
Doctor Who, both old and new. Loved Blink which is the most recent one I've seen. I have been wondering why I'm so reluctant to catch up on shows. I guess it's because I don't want to be disappointed. I hate getting excited about an ep or a show and then have it turn out like CSI.
Torchwood: I only recently noticed that I missed a few episodes in the middle of the season. Quite a feat with such a short season, but I still managed ;-)
Las Vegas: On the list of things to be watched.
Crossing Jordan - Season 6: The show never was good as far as crime dramas go. Still, it should have been released on DVD, if only that would have made it easier to get my hands on the episodes.
Stargate SG-1 Season 9 second half, Season 10: I have a love-hate relationship with this one. I've stopped watching several time, only to come back to it every time. I figure I'll eventually watch the remaining episodes.
There probably is more, but I can't think of anything right now.
