The author of the following article, Glenn L. Diaz, BuddyTV Staff Columnist, seems to think so:
"....When CSI: Miami returned September 22 for the premiere of its seventh season, the reviews were mixed.....According to TV Guide's Matt Roush, “no one's really expecting Emmy-caliber work here. But from the critical fence on which I sit and contemplate the current crime-drama glut, I have to set the quality bar somewhere. And this show no longer clears it.”
.......He even surmised that perhaps David Caruso infuses what is called the “Shatner effect” in reference to actor William Shatner, who isn't a particularly compelling thespian but still had people riveted when watching him...."

Quote of the day - As for CSI:Miami…David Caruso is good for a laugh on Sunday afternoon when you can’t find anything else to watch. (http://carriev.wordpress.com/2008/09/30/random-thoughts-2/)
