Just got back from Imax 3D. I wasn't really interested after the trailer because it was hard to tell what story was there with them floating in space. Reviews were great so I gave it a shot.
Definitely worth going to see! Very tense throughout. Great performances and clearly it's visually amazing and has some really well done shots. I'd say it's emotionally draining. When we stood up I was surprised it hadn't even been 2 hours since we sat down.
