If you are a Star Trek fan, there is plenty to like. In particular, Dr McCoy was great. There are other great injokes and plot points that are put there just for you.
Due to a time travel paradox, this is a different Star Trek than the original series. The characters are very similar; but not the same. And the universe has been irrevocably changed in ways that will give future movies new plot points to follow.
I'm looking forward to future movies with this same crew.
