I liked Vantage Point even more than I thought I would. I don't understand why it didn't get better reviews in general...
The story is told many times, from different point of views. Each time more information is revealed, sometimes correcting what we thought we knew about the events we have already seen. So there's several surprises during the course of the movie, which I liked. It's hard to talk about a scene without giving out a spoiler, but I remember one instance where we are shown an event and I was sure I had figured out the twist, which a following scene proved me right, but then another one later revealed another aspect I had not even considered for that same event.
The short version of the story is that a world conference where world leaders gathers, in front of a crowd, turns to chaos when the US president is shot. We see the events prior, during and after this shooting from the point of view of the president, a Secret Service agent, played by Dennis Quaid, some spectators, including one played by Forest Whitaker, the people behind the shooting, a news crew and a few others.
If you can figure out what is going to happen before it happens, you are a much better detective then I am, because they surprised me, even fooled me, several times. There's also many good action scenes, including car chases.
