The holodeck was somewhat gratuitous, to bridge the TOS era to TNG (as was the counselor). I can live with it. We had the IDIC scene in a broadcast TOS after all, just to sell trinkets.
I'm ok with a different-feeling Dr. oddly. I really like DeForest Kelley; but different actors are allowed to interpret a role differently. In fact in the movies Pine and Quinto seem different from the TV actors, but Urban is so Kelley-like, it takes me out of the story a bit. Weird, I know. The Chekov guy, too, like they're impersonating the TV actors while the rest did their characters on their own.
