Although I loathe a lot of what Hollywood does in films these days, I am willing to put up with much of it as long as the film pays off in the end. While there is much to admire in The Departed, the ending is one of the worst I have ever seen, below the standards even of Training Day and John Q. I was quite mesmerized up to the point where Costigan discovers the truth about Sullivan. In spite of Scorsese's compulsion/obsession with every filthy aspect of human nature, I was very much enjoying the performances and the story. Then, it seems he or the screenwriter had a brainfart. In light of that fact, all of the excess of the film caused it to implode. In the ensuing vacuum, I could find no redeeming quality of the film at all. What does the story tell us? It wasn't true to itself at all. No one gained a thing. No redemption. No resolution.
I am not an expert on films in any way. But it seems to me that when a story is developed on the strength of a collection of main characters, the story had better wind up focusing on the relationship between them. One by one, the supporting cast is eliminated. Then one of the three main characters is killed off. That leaves the two lead roles, and as far as I'm concerned, at this point it has to come down to the two of them. Whether it's a showdown or a meltdown, this film had to close with Costigan and Sullivan forcing the outcome. Instead, they are both eliminated with as little drama as if they were innocent bystanders. The fact that these events left as many questions as answers tells me that the director really didn't know what he wanted the story to say.
The acting was superb, the story captivating, the suspense almost unbearable - what more could you want from a good movie? Well, as far as I'm concerned, without a good ending, all of the above amounts to little more than the hype that usually precedes a film, but in this case makes up the bulk of the film. Enough with the blood and guts, Mr. Scorsese, enough with the profanity and vulgarity - lets see if you can make a film that succeeds on its own merits.
And in the meanwhile, I would appreciate it if you could convince the studio to refund my money.
