I wasn't particularly enthused about this one but liked it - liked it a lot. Didn't find it to be as predictable as others - thought it nodded to earlier films but didn't rip them off, and I thought it unspooled at a good pace. Not too fast, not too slow - just quick enough to give us an interesting story and let us follow its path.
Yes, Cruise does "play Cruise", but he's still fine in the part, and he grounds the film.
Much more involving than I expected, and it had a lot more heart than the average sci-fi/action flick - I got a bit choked up at the end and found it to be emotional.
Probably the most enjoyable 2013 film I've seen so far...
