Won 4 Oscars? Why?

Rating: 3/10 (23 September 2010)

I just have seen "Departed" and I am pretty annoyed. That is for different reasons and I know, that many people think different about this movie. Just my humble opinion. *I could not believe the story.They knew everything about Bill Costigan (De Caprio), about his relatives, his past, about his psyche, they nearly investigated every fart he ever did. But they knew nothing about Sullivan, although his entire past is linked to the bad guy Costello? Why did Costello believed Costigan? Why was Costigan so violent toward the people in the shop? To make his disguise/cover work? *How could anyone suggest Wahlberg as the best supporting actor of the year? For what? Forcursing? All this cursing did not help to create tension or to bring the movie forward, it is just ridiculous. *I do not like the ending of the movie. They are making up a useless twist to make the story look more intelligent as it is. Is a movie more sophisticated when you kill the good guy?
There are some good scenes in the movie, but it did not work for me. Just my opinion, but most Scorcese movies are depressive, violent and left you behind with a melancholy emotion.
Definitely not worth 4 Oscars.
