NBC has been bleeding out for a while.
The last CSI LV I saw was a few weeks (maybe less) ago when the one guy was killed by the old white cop and he tried to blame it on a convict and get him to mexico.
I don't know LV enough to drop detailed names but I can give you an idea. The guy who just left (gill?) Was one I had an issue with. His acting was bland imo. Like he tried to capture the character, and in some ways he did, but he doesn't play the "troubled" guy well at all. Its like he tried to hard and it came out bland anyway.
And there is the one girl. If you refer to the same episode she is the one who asked the lab tech to leave the lab so she could match the partial on the casing (.22?) To the officer they had as a suspect. She is good more then bad, but sometimes she just annoys me.
