Cruise is always reliable but Blunt was a surprise (I didn't think she could pull it off based on the trailers). well-done pace and editing helped. 3-D was immersive, and I'm a big opponent of that effect in general (The Hobbit 1&2, Gravity and Pacific Rim are the only movies I've seen in 3D the last two years).

the premise falls apart quickly, but it's entertaining within the moment. I've already forgotten most of the movie, however.
