User ratings on Rotten Tomatoes are about as useful as YouTube comments. If you're viewing a page for a movie after the movie has come out you're not part of the general audience. You're most likely a fan and that's why almost every movie on Rotten Tomatoes has a positive user rating. Even After Earth is sitting at near 40% positive with a 2.9/5 rating.
I agree that Into Darkness was well received by general audiences, but the user ratings on that site should be ignored.
So you have 230,000+ fans who enjoyed the movie then. Which, to me, gives even less credence to those fans who say Abrams and Company are ruining the franchise.
But, I really haven't seen a bad review of the Abrams films outside of fan sites. So it seems we're down to some die-hards that are mad because we aren't getting more from the same people who brought us Insurrection
