This is the first CSI episode I've ever watched where I actually had to cover my eyes and ears. The torture scenes were totally creepy and, IMO, unnecessary. I thought they were trying to bring in new viewers with this episode. If I were a new viewer, I would have turned away as soon as I saw the first torture scene. Maybe it's just that I'm too squeamish, which I don't think I am, but that it was so different from what we normally expect from CSI. It felt like something from 24 or a horror film instead. If TPTB are going to market an episode as much as they did for this one, they should really try to make it more family-friendly, IMO, so that it appeals to a wider audience and can actually bring new viewers in, and they should also make it more similar to other CSI episodes.
Also, the juxtaposition of creepy torture scenes with more sentimental goodbyes was just really weird and made it feel, IMO, very disjointed. I liked Grissom's exit from the Lab, though I'm still really undecided about the GSR part. It felt very out of place to see him in a totally different environment with a funny monkey staring at him. I expected that the GSR would be the biggest disappointment of the evening, but somehow that actually turned out to be (almost) a highlight, just because it wasn't overly dark.
Overall, it felt to me like it was a weird collage of different movies/shows -- extremely creepy torture stuff, happy sentimental dramedy (GSR) combined with what I normally expect from CSI (the forensics and other characters).
The forensic astronomy was cool and I thought LF did an excellent job, as did the rest of the cast. I'm still undecided on Hodges as well.
Still, to me, all of the torture and gruesome stuff outweighed what should have been a very memorable exit for a wonderful actor. Overall, I was very disappointed.
