Okay, well, back to a more normal CSI week, this one will likely go down as nobody's favorite episode, for any number of reasons.
I didn't enjoy the episode because it was one of those "everyone ends up dead or in jail" deals. Very few misleading or "extra" players, the mystery being more in the "who gave crabs to who" and "who was in the video". Every character (outside of the unidimensional parents) was involved in the crime, and that sort of made it a little too easy. By half way through it was "yeah, yeah, they all did it".
I also thought that the opening sequence dragged badly, took way too long to play out, and set a very slack tone for the whole episode.
On the plus side, pretty much everyone got in the game, everyone got a piece of the puzzle and everyone got a few minutes on screen. A good team play episode, which after all the strife over the last 5 or 6 episodes, this one looks good.
As for the GSR: I think the writers have handled this one well, giving us glimpses but no full on liplock / sex scenes to deal with. Enough exposure so that if Sarah leaves / dies / whatever, there would be loss. It is easy to speculate on any number of ways this thing can be used. Overall, I think they hit this gently but clearly with this episode. If you don't like GSR, then you didn't enjoy this episode.
Overall, this episode for me is a mixed bag: Great team effort, some GSR, some nice lab work and facetime for supporting characters, but on the downside, well... the crimescene storyline was poorly developed, a lack of extra characters outside of all the obviously guilty ones, and a horribly long opening scene. This for me is likely the weakest episode of the season.
