I saw The Departed yesterday afternoon. One of Scorsese's best . . . even though the ending left me a little flat and there was one loose end that just didn't make sense.
Killing DiCaprio's character and two other supporting characters was way too tidy (figuratively, not literally). Damon's character needed to get his comeuppance. And, since Damon's girlfriend had the goods on him, why didn't she turn him in?
That said, the pacing of the movie was non-stop without being tiresome and the dialogue absolutely crackled--the exchanges between Martin Sheen, Mark Wahlberg and Alec Baldwin will be quoted for years (albeit not in mixed company). Matt Damon and Leonardo DiCaprio as two different tormented souls have never been better and Jack Nicholson--well, Jack was Jack at his scenery-chewing best as the mob boss Frank Costello.
As Max said, The Departed is old school Scorsese, so the violence is intense and pervasive and the language is profane. I was stunned to see two parents sitting in front of us at the theater with their two small children.
Highly recommended (the movie, not bringing your kids). Go see it.
