It's a good film - went and saw it in 3D. It's not a great film though - it's not a Star Wars or an Indiana Jones, with the more subtle interactions that characterise those (original) movies. Instead, it's more a technological tour-de-force, with a fantastically designed environment - everything about it pulls you in, the plot, the music, the atmosphere; so that by the end of it, you've just watched 2 hours and 40 minutes, and don't even realise it.
Sure, if you're a snobby, elitist jerk who goes to movies to be educated, enlightened or otherwise intellectually jerked off, it's not the movie for you. But then, nor is most of the other stuff that has come out in the past 130-odd years of movie making. For anyone else, it's a great popcorn fuelled roller-coaster ride that grabs you by the balls and carries you along all the way through to deposit you, wondering quite what happened at the other end. If you're in the UK*, you'll appreciate the comparison: This is the Nemesis of movies.
It also, possibly, could be good in another way - it'll drive 3D into homes. Once the Blu Ray hits, and assuming the Blu Ray 3D design has been implemented and that devices are available to play it (All big if's at the moment), people will want to see this 'like in the movie theatre'.
All-in-all, I'd call it a significant film.
* If you're not in the UK, Nemesis is a very expensive roller-coaster that was built at Alton Towers, had a lot of stick while being built for being so expensive, got huge recognition now that it has been built and running, and made the theme park bucket loads of money.
