Either you love it or hate it, I loved it... Magnolia is one of my personal favorite movies. But after reading some of the reviews here, and after talking to friends who have seen the movie, it is definitely not for everyone. A lot of people complain about a convoluted story, or pretentious direction, but to each his own.
Let me explain why I liked this movie... First off, I don't watch movies just to be entertained. Entertainment is part of the experience sure, but that is not the sole merit by which I judge a movie. Art is about creative, emotional, political, and surreal expression. Viewing/listening/reading art is about your personal interpretation of or response to it and about how it affects you. Second, I believe good movies are not defined as good movies because of what they are about, but because of how they are about them (hopefully that makes sense).
For some reason I was inexplicably drawn to Magnolia. All of the emotions expressed throughout the movie were so tangible and relevant to me. The style of direction and overall story arc of the movie is a bit exaggerated in comparison to real life, but the emotions expressed through the actors and the situations they are in are the most real and profound I have ever seen in a movie. The reason they were real, profound and relevant to me is because I could easily relate to most all the emotions and feelings in the movie, they correlate to feelings and situations I have experienced in my life.
I didn't just like this movie because of the emotional connection and intensity though, it is also an extremely well directed, well acted, well written, funny and entertaining movie. P.T. Anderson handles multiple characters and storylines with skill comparable to Robert Altman, and successfully creates one of the most amazing film experiences ever. But as I stated before, this is not the type of movie everyone will enjoy. People who only watch movies to be entertained, or people who require a coherent and straightforward plot will probably not like it. Overall I rate it **** out of four stars.
