NY hasn't really happened yet. But as has been said, Gary Sinese is a solid actor so it has an ok chance.
The original is clearly the better series. The scripts are better. The characters are better and make sense. (There's a solid number of nerds, and semi nerds involved...which makes sense because they are science geeks.) And its just more polished and refined. The actors for the most part look like they might be people who do this. Sarah with her gappy teeth looks like she could have her geek side, grissom goes without saying, greg I totally buy as a lab nerd, the rest are at least ok.
Miami is just trash...I love the original but I just can't get into Miami. David Caruso clearly thinks he's still on NYPD blue and has just forced his science geek character into a generic hard ass cop role which seems to be the only thing he's capable of doing. The rest of the characters are ho-hum at best, mostly existing as pretty-boy and pretty-girl cast who just spout drivel and disappear to allow caruso to lean on some generic guy after jumping out of his hummer. I mean I want to like it, but it just throws the concept out the window and becomes another generic cop drama full of over/bad acting with a little bit of science stuff thrown in.
When you think about it though CBS execs are really quite smart. What happens when an innovative, successful idea comes out on TV? The other networks copy it, flooding the airwaves with the same stuff until the public hates the idea. After its used up, they move on. CBS knew this would happen after CSI was so successful, so they just beat the other networks to the punch. They flooded the market with cheap copycats of their own idea, leaving no room for the other networks to get a niche. Will they burn up the idea quickly? Probably. But at least THEY will reap in all of the advertising dough instead of the other networks just riding their coat tails.
