Saw this movie a few days ago. It's a nicely done heist movie. It skips act 1, instead making the "who is the team" part of the mystery. A few of the parts are rather thinly motivated, like that of Jodie Foster, but this is just entertaining fluff. With plot fluff character development can be left very thin. The filming is skillful. The plot is suitably concealing of the plot tricks, while revealing enough to be interesting. It's a good entertaining time. If you enjoy movies, it's worth the cost of a ticket. If not, it is definitely worth renting.
It doesn't compare well with classic heist movies like "Asphalt Jungle". It has more technical filming expertise and a much more complex plot, but the characters are paper cutouts by comparison.
