CSI LV has lost it!!!

Ok so i'm in the Uk and we get the new episodes of CSI las Vegas later that the USA and i have 2 say from the episodes i have seen the show seems to have lost it!!!

I knew that when Grissom left it would be a big challange for the show to keep up the high quality of stroylines ect.. but what has happened.

Each episode now seems to focus on the team standing around discussing the crime rather than actually going out and investigating (i know discussing it is important but that isn't what the show is about). When lawrence Fishbourne joined their was alot more actual investigation but that seems to be declining now again.

Why don't they invesitgate 2 crime scenes in 1 episode anymore? Why doesn't Catherine get more involved? What has happened to Greg's personality? And why has New girl Riley become such a boring, Pointless addition?

This once great show seems to be decling fast, i really hope there are big improvements in the future or i may stop watching. Less Talking and dim lighting, and more action and investigation!!!
