The new trailer is better than the 2nd trailer, the first trailer with the Enterprise begin build is better then both.
The new trailer bugs me because it shows me that the movie will be bad. I have watched The new trailer many times and at first like it, but then I Re-watching it and it started to bug me. The New trailer can be designed to put a different spin on the film, but the thing is that the New trailer has less dialog then the last one. The Last trailer and The Prequel comic (countdown) shows how the dialog (and story-telling) will be in this movie.
Watchmen was good, but it does not mean This Star Trek film will be the same.
Being skeptical is Wise, but I would wait to read reviews (by fans would be the best) on this film before spending a ticket price to see it in the theater.
Remember the best thing of Star Trek Nemesis was it's trailers (which looked like a Mirror-verse TNG movie).

Side Note:
Just Re-watched the 1998 Lost in Space movie which was a So-So movie (bad but had some Ok parts). The one of the OK part was Gary Oldman as Dr. Smith. Gary Oldman play it like Jonathan Harris' Dr. Smith (mainly the Dr. Smith from the pilot).
It is odd that a big and known actor like Gary Oldman played Smith like the Classic Smith, but then a little and unknown actor like Chris Pine is not playing Kirk like the Classic Kirk (WTF).
