I'm just going to come out and say it, this was an awesome popcorn flick.
The visuals were stunning. It probably helped that my friends and I went and viewed it in IMAX 3D instead of going to a local theater. Thank you time off for Christmas!
The story was, well, let's say at parts it was telegraphed and you knew exactly what was going to happen. It wasn't ground breaking by any means, but this movie was more about the spectacle rather than the writing. That being said, the story wasn't a solid steaming lump of excrement like say, oh I don't know, Avatar.
All in all I enjoyed it and would recommend you go and see this one in the theater.
