I didn't really go into "Reign Over Me" knowing exactly what to expect either from the director or the story. The plot was easy enough to understand, I suppose. This guy's whole family died in 9/11, and he shuts the world out of his life. Alright. I didn't know if it was going to use the attachment of terrorism as a platform to speak on that or other issues relating to it, and it really doesn't on a very obvious level, so if you're scared to be surrounded by political opinions that may be different from yours, I wouldn't worry about it. I think the writing even made a point never to explicitly mention "September the eleventh".
Overall, I was impressed. It was a very moving picture. The movie has a sense of humor, and it is very sharp, but it is definitely a drama where it counts. I typically don't like to think that comedic actors are incapable of actually acting, but sometimes, let's be honest, they are. Adam Sandler is definitely capable of it (and though I think so, you may disagree, Jim Carrey is also very well-rounded.. sometimes). Sandler's portrayal of Charlie Fineman took a character that on the surface seems completely unreal and makes it become absolutely believable. I read many reviews that criticized the writing of Alan Johnson's (Don Cheadle in another excellent role, if not one that seems similar to a few of his more recent pictures)wife, who is played well by Jada Pinkett Smith, calling her static and dull, but that is completely untrue.
She has depth, but some of it gets hidden behind the main story, which does drift in and out of focus occasionally. (Which also brings to mind some very unusual transitions done early in the movie, with a weird "Make everything out of focus" fadeout. After about the first 40 minutes, they aren't used anymore. Maybe it's significant for the characters outlook, artistically, or maybe they just realized how irritating it was.) The film gradually begins to reveal to us the point (one of several, but definitely the most explicit) of the story, which is that sometimes people have to deal with grief in their own way. Maybe it seems unorthodox to us, maybe it seems downright unhealthy, but maybe what some people want more than anything is just to forget. To just exist. The films soundtrack was excellent, and it used music to pursue and amplify moods, rather than establish them, which gives credit to the actors and the writers.
The movie takes it's name from the song "Love, Reign O'er Me", off of The Who's rock opera, Quadrophenia. The song itself is fairly insignificant to the actual story, but it is used powerfully in the movie over the course of the climax, and at the very end. The movie is paced well, and does not feel like it's dragging anywhere in it's length, which is a little over 2 hours. If you can accept Adam Sandler's portrayal of this deeply heartbroken and broken down man, you will enjoy the movie. You will become entangled in the story, and you will genuinely feel for the characters in every minute of it. It is not the best movie of the year, and there's nothing groundbreaking or positively amazing in it, but it's a very enjoyable, watchable movie, all in all.
