It's holding up fairly well on Rotten Tomatoes with a 67% as of this writing.
Not great by any stretch, but surely a lot better than many were expecting it to be. And I know you shouldn't put a lot of weight into early-screening reviewers for obvious reasons, but I've read various posts from users on other boards who've said they really enjoyed it. I'd take their word over studio-handpicked test-screeners who know they probably won't get invited to future screenings if they talk bad about the film in question.
So... I guess I can safely go in cautiously optimistic next weekend? Which is more than I can say for the last few films.
