"21" is a clever story with reasonable twists and turns. I guess executing such a film project could be no brainer since the script was based on a true story.
Keven Spacey's performance was as sharp as a knife but not as electrifying as before. This could be forgivable since the focus should be on the MIT math genius, Ben Campbell (played by Jim Surgess).
I wonder whether we could criticize any cliche inherent to the plot, given that we are talking about a true story here. What surprised me most is the seemingly humble intention of the filmmakers, who only tried to tell a good story concisely. So, we may call it a fairly entertaining movie, no more and no less.
