Saw it for the fourth time today with my sixteen-year old son (first time) and he loved it.
The second, third and fourth times I've seen this film I've been fully aware of its shortcomings and have expected them to impact my enjoyment, but they haven't. This is a movie that simply grabs hold of you and doesn't let go from beginning to end. The cast is incredible. I could go again tonight to see it!
I just don't know how you can say you're a Trek fan and not enjoy Into Darkness on at least some level.
Careful now. If we get to protest the "real Trek fan can't possibly enjoy Abrams Trek", shtick, you can't give them any ammo to make the same argument in reverse.
