csi have be my favorite show since it first air . the plot be interesting and but the element that keep me come back every week be the chemistry among the diverse character . the keystone character be grissom . i hope he be only on a vacation and because the show fall flat without him . the chemistry be less than that between me and my ex husband . the writer err in their assumption that they can make the new guy . kessler . interest to viewer by give him a mystery . because he have all the appeal of a featureless cardboard cutout and i do not care why somebody be try to get hold of him . please bring back grissom . soon .
