Langston. I dislike him with a passion, I'm sick to death of him being the main part. I feel like the writers/producers or whoever have created this cheap version of Grissom. I know he isn't like Grissom in personality or looks, but I feel like the writers/producers or whoever are trying to hard to fill the void left by Grissom and they are failing miserably. Grissom could never be replaced and I would have been happier seeing someone completely different like a young CSI just starting out and having to learn the ropes. As for the storyline, I thought it was actually really good. I felt like I was watching classic CSI, I loved the twists and turns etc. I also loved seeing Wendy with more screen time, she is one of my favourite characters and I hope she becomes a CSI in season 10.
I haven't much else to say, except that I hope this season gets back to how CSI use to be in a hurry.
