As someone who has been a fan since the original series was in first run and has seen every episode and movie of all the Star Tek incarnations I will say I was impressed and surprised. Star Trek has been given a new start(everything you knew before is now subject to change) and this has been done in a "believable" (for sci-fi) way. Confused? Go see the movie but again, forget everything you knew when you walk in to the theater. This not the Star Trek you have known and at the same time it is.
As a sequel "The Dark Knight" surpasses "Batman Begins" which is saying a lot. Both films take a more serious approach to the Batman legend when compared to the first five films. Heath Ledger gave an amazing performance as the most depraved Joker yet. No surprise that Morgan Freeman is a great supporting character as Lucius Fox the man who develops Batmans "toys" and continues to pretend he doesn't know of the dual identity. Also no surprise that Michael Caine and Gary Oldman play their roles as Alfred & Commisioner Gordon with the easy grace of the consummate actors which they are. Even with the wealth of talent in this cast the movie surpassed all expectations. I would have to say "two snaps up and a circle!"
