I saw the movie a few weeks ago. I would definitely rate the movie as "Above average" compared to other summer action movies. However, as a fan of the Trek universe I was a bit disappointed. I suppose if it had featured a cast from one of previous series I was more familiar with I would have rated it much higher (i.e. bias). For instance, I didn't like how Spock turned "rogue" and just rejected most of the values he was raised with. Spock as a kid was cool though. The canon issues aren't a big deal since the movie takes place in an alternate timeline. But I'd much rather have seen a movie that *could* be canon. Still, I wouldn't call the casting "bad". Except for Scotty, the casting was "believable" in terms of everyone being younger versions of themselves. But maybe only for an episode. Putting them in a whole new movie without any prior exposure to them was a bit jarring for me. Even the "New Voyages" fan episodes didn't affect me to the same degree (though this could be because they retained the same basic formula and the same set as the original series). I guess what everything comes down to is whether I would go see another movie featuring the same cast/director. I could only give you a "maybe", or a "likely" given that there's not much else out there I'd want to go and see. My 2 cents.
