It's all about NCIS for me. I used to love CSI Vegas, but I dunno, I just lost interest in it. Miami and NY annoy the hell out of me, especially with David Carusso's cheesiness and sunglasses.

NCIS seems to have a better cast of more diverse and interesting characters, and I love how they slowly reveal little tidbits about the characters, while injecting some humor into what could have been a boring series.

I also loved NYPD Blue when it was on, and Third Watch... and Boomtown. Now THOSE are some great shows. Third Watch and Boomtown were short lived though.
