I don't think he watched it in IMAX 3D, because only in that form can you completely appreciate the movie's absolutely breathtaking visuals. It really captured the bleak nature and vast emptiness of space. The soundtrack was also excellent. I suppose the story was nothing too special.
Exactly, that movie scares the shit out of me more than any horror movie because space is space. The exorcist and all movies of that nature can go suck a mullah's ****. Gravity has alot of scientific errors but that doesn't take away from the horrors of space.
A movie I saw recently that I'd recommend is "The book thief" very beautiful movie but not for everyone. I haven't read the book but I hear the movie did it justice.
