I understand addiction.
I would even go as far as saying that I have an addictive personality. That is, I can easily become addicted in one way or another to certain people, places, or things.
But I can never understand drug addiction. You have to let that happen. You see it coming, and it's hurting you long before you're a "junkie".

Requiem For A Dream is about junkies. Jared Leto is the central figure in the movie. He plays Harry Goldfarb…and this movie revolves around Harry, his girlfriend Marion, played by Jennifer Connelly, his best friend Tyrone, played by Marlon Wayans, and his mother, played by Ellen Burstyn. The movie is directed by Darren Aronofsky, who brought us the critically acclaimed "Pi" (OK, I tried to insert the "Pi" symbol, and it didn't work, OK?!?).

This movie is full of great acting. Jared Leto is very impressive. I hear he lost a lot of weight for this movie. He seems to be another Johnny Depp, or Brad Pitt, whom Leto costarred with in Fight Club. Here's a studly guy that chooses weird roles in which he looks less than studly.
Jennifer Connelly is also impressive here. She has a hard role to pull off, but she does so well. Marlon Wayans really surprised me. Best known for almost slapstick comedy, Wayans definitely is not comic relief in this movie. In fact it's an extremely dramatic role, and he pulls it off superbly. I never would have expected him to be able to. I'm sure he will raise a lot of eyebrows with this role.
The stand out of Requiem for a Dream is Ellen Burstyn. She is simply amazing as Harry's mother. She seems a shoo in for an Oscar nod.

Darren Aronofsky is a very talented filmmaker. His visuals hook you in. He's so daring…almost like a cross between David Fincher and The Wachowski Brothers.
I can't even relate how excited I am about his apparent involvement in the not even in pre-production Batman 5. I think he will definitely bring that dead franchise back!

Requiem For A Dream is not an easy movie to watch. It shows you things you do not want to see. But if you appreciate good movie making, it's a movie that should not be missed.
