It is OK. I am not a big CSI fanatic, so I didn't have very lofty expectations.
The initial set up was cool where you mapped out the crime scene, but it doesn't seem they are taking care in these sets. There was random trash from customers littered around, which wasn't part of the crime scene. The puzzles which followed were somewhat interesting, but not very challenging. The autopsy part was pretty cool. The workers for the experience seemed very vanilla. You could tell they put in many endless days at this place, and they seemed to be rushing you through the part at end on computer.
This would probably be great for kids 8-14ish
