We are huge CSI fans and I found part 1, season 8 really was disappointing after the usual quality. The build up to saving Sara Sidle was little disappointing, it could have been better.
Many of the story lines are weak, with a good story toward the end. The episode where Sara Sidle leaves is good as is the story line which crosses both CSI and Without A Trace is the best on the disk.
It was too short as well, so value for money just isn't there. This isn't reflected in the price (thankfully we picked it up on sale before Christmas for a little over £10, but the price has since jumped back up again) There are some bonus features including a Without A Trace Episode, one episode with commentary, a feature on Sara Sidle's departure and also a special director (which is relevant to season 8 part 2 not part 1).
The final episode on the disk is terrible and it is really disapointing to end with it. It may have been an attempt to do somthing 'light' after Sara leaves but I found it really hard to sit through.
I am hoping part 2 will be a lot better. Wishing I waited for the release of the Season 8 Box Set.
