I'm always intrigued by small titles, because sometimes they're better than the big moneymakers. This one failed to disappoint, especially because of the superb acting and camera shots. Vincent D'Onofrio(still "the bug" from "Men in Black" in my mind) did a wonderful job of stepping out of that role and into one that's believable, despite Sam's odd story. The first time I watched this, I was intrigued by the possibility that Sam may be telling the truth. Fortunately, K-Pax hadn't managed to ruin that scenario completely for me. The ending was a complete surprise and there were some nice twists.
I picked this up again to see if it was still as intriguing and to my surprise, it was. Even knowing Sam's true identity takes none of the emotion out of the film. I saw that this movie is not just the audience deciding whether or not to believe Sam, but Ruby deciding as well. It's a terrific inner conflict for her, as she struggles in the face of love and honesty after a string of horrible men. Haven't we all met someone that we loved and wanted to trust, but we didn't know we could? The time travel aspect makes this movie impossible but the characters are so real and deep, then the movie feels real and you find yourself thinking if only for a moment that it is perfectly possible. That's why I say that even if you know the ending, watch this movie for the quality that it is.
