I found this episode to be very unimpressive. Liev Schreiber does quite well in the first episode of his guest stint on the show. Kepler appears to be very similar to Grissom in the sense that he is very low key and analytical and I like that. What I didn't like in this episode is the absence of the good writing style that we have seen quite a bit in the past on CSI. This episode seemed more focused introducing Schreiber's character than giving the viewer a good story to get involved in. I hope this flaw will be corrected in future episodes.
