CSI needs a new spin off?

Some CSI series have changed lately. The original CSI changed completly this year as the leading actors changed. And to my taste, it was a refreshing change. But I would not want Horatio Caine to be removed from CSI Miami, although he is absolutly predictable.

There are 3 CSI shows and none of them are doing as well as they were in the beginning, they have Miami for flash, Vegas the original and the most balanced and New York is always intense. It would be difficult to bring in another show, it would be possible to add or remove actors, give more variety to the crimes investigated and more crossover shows, but this could make people stop watching. I suspect that CSI Las Vegas lost a lot of viewers when William Petersen(Grissom) left. Who knows, when the youngest of the shows - CSI: NY - started many thought it wouldn't last and it has been around 8 years, and after 150 or so episodes and CSI : Las Vegas with 250 or so it is not surprising they start to repeat themselves.

It is ok...it is always difficult for this kind of show (with long history and large group of audiences) to have breakthrough. I think the production team has already tried their best to add in something new, like inviting guest stars to perform in the show (Justin Bieber is very fresh, right?). Maybe for some of us, what we need is something new in plot, in the way how the killer murdered somebody, but if we think in another way round, if the way is "TOO" new, then the show is not authentic enough because no one else in reality will kill somebody in such a way. So if you really find it boring, then go watch some other shows like NCIS LA.
