First of all, I love this movie! For the sole reason it is nothing like the American movies we get nowadays. Watching this movie you can't help noticing that fact.
One reason is that this movie doesn't quite make sense. The ending is so amazingly different to anything, contrasting even the movie leading up to it.
The other reason is that the techniques used in this movie are never used by American directors. Why? Because they think it would make the movie boring. And a lot of people will find it that way.
If you want a movie to contrast all other movies in your DVD collection, this is perfect. You'll never be able to quite figure this movie out.
The reason I didn't give this movie 5 stars is because it doesn't have global appeal. Too many people will be bored to tears.
