Sometimes I feel like I have to watch a lot of Asian thrillers just to find one that really works. For every 50 or so I watch, there will be only one 20th Century Boys or Confessions. The film works on pretty much every level, though it might be a bit hard to follow for some.
The story starts with a pretty simple event. What you're completely unprepared for is that such a simple act will spiral completely out of control into an incredibly twisted series of events. You see...this is one of those movie that will tell (relatively) the same story from different angles and perspectives. That bit may throw some people off, but I promise it all makes sense if you're paying attention. And you should be paying attention, because watching the whole thing unravel is a hell of a lot of fun.
Every movie has at least a couple drawbacks, however minor. One minor thing that kind of irritated me was the frequent use of slow motion shots. I understand using it to emphasize the importance of a shot, but this is just a little out of hand. Also, I wish some of the alternative tellings of events happened more linearly at some points. In some cases results are shown before the audience has a chance to even follow the story line to what leads to said action. But those are both minor nitpicks, really. On the whole, the movie is just plain excellent.
