There are 3 CSI:'s : Las Vegas, NY, Miami. Which one is your favorite? And why...

Mine, all of them..

I like CSI: Las Vegas because of the amazing veterans characters. They are still great.
I like CSI: Miami because crimes also deals with money, drugs, mobs and gangs.
I like CSI: NY because crimes relates to today's trends and cultures. It's more on an urban crimes.

Mine is CSI Miami - I love the characters of Horatio and Caleigh.

Funny, CSI Miami is the one that I simply can't watch! I find the star's mannerisms too annoying to get past.
CSI Las Vegas is still the best to me, although I like the actors in NY even though the story lines are pretty far out (and I'm a born New Yorker!)
Do you know that there is a CSI Caracas in South America?

I still remain loyal to the original CSI. I've tried watching the other two but just couldn't get into them or the characters. I don't find this franchise as good as the Law & Order franchise where I can watch any of them.

I like Miami first - was not a Caruso fan before, but this show I like him in. Then Las Vegas..Grissom...what can you say. NY I never quite took a liking to it. Although Gary Sinese is an awesome actor, this show...doesn't cut it for me.

I love the Vegas show, and eventually warmed up to the New York cast and story style. But Miami bugs me. The story lines always seem a bit TOO far fetched and Caruso's acting is horrendous. He's so cheesy, my fiance and I (who have a household nickname/shorthand for everything) simply refer to CSI: Miami as "Velveeta." That said, I do watch it sometimes, just to crack jokes about Caruso's acting and 'cause I'm a bit of a CSI junkie...

CSI - Las Vegas. Grissom is my fav character. I don't care for CSI-Miami. Caruso is too arrogant and doesn't come through for me.

For me, the three shows are interchangeable so it is more a matter of which actors I feel like watching. My first choice would be NY, mainly because I like Hill Harper. Las Vegas would be next, but I'm a bit bored with that cast. Miami is difficult for me to watch because Caruso's mannerisms are off-putting, as others have said.

I'll take the original.

I only watch Miami when I want to laugh (at Caruso's acting, that is).

I've never really gotten into NY (even though I do love Gary Sinise).

PS - Here is Jim Carrey on Letterman doing David Caruso impressions.
