Maybe I should be a movie critic?

The Departed:  A-
The casting of this movie was STELLAR!
Before paying one ounce of attention to the plot, I noticed the cast!  Matt Damon, Leonardo DiCaprio, Jack Nicholson, Martin Sheen, Mark Wahlberg (aka Marky Mark)... how can you go wrong?!  Once I went online to read what it was about, I decided to spend the money and see how it was.
My mother had seen it a few days before and said that it was a little confusing and every other word was "Fuck"... sounds like my type of movie!
So... without giving it away, let me just say that it was a great movie!  It's about the mob, it takes place in Boston, and there is a LOT of shooting and 'foul language'!!  Matt Damon plays a bad guy who works his way into the police force (to investigate the mob he is part of), Leonardo DiCaprio is a police officer who works his way into the mob!  Jack Nicholson is the mob leader.  The two don't know who each other are and they are both trying to find the moles within the two organizations.
The story could be easily confused if you are not paying attention; for the most part it's pretty easy to follow!
It is a rather long movie, though hardly noticed by the time it is over.  Coming in at 2 1/2 hours, make sure you buy the large soda and use the restroom before hand.  It was hard to pick a time to get my refill!!
Anyhow~ I'd give the movie an A-, I was entertained the whole time, and the story was very good... and I supposed for 2.5 hours of film you can't really add much more story to that.  I gave it an A- because of the really bad Boston accents, and Marky Mark being such an ass!! 
All in all... great movie, I highly recommend it!
