Man, check out the debate on the CG Society site. Highly entertaining!
I have very very mixed emotions about this one. Nobody can recreate TOS. Replacing the cast is just impossible, but maybe people too young to have been captivated by TOS won't compare and therefore won't care. I really want to leave the old gang behind, or have them included in a few rare cameo scenes as retired officers or whatever, but don't revisit the old Enterprise with a fake crew. Just don't! There are some things which should not be touched, but I guess money talks.
On the other hand, the Star Trek franchise needs to come back from the dead. Certainly, a lot of CG stuff can be done today looking much better than before. But Star Trek was never about mainly action and flash. We need good character development, and the exploration of large issues facing mankind. This is hard to do with today's state of cinema and network TV. I liked Enterprise, but only caught a few episodes, no idea which season they were from, but sadly it has not caught on...
