Sideways is truly looking at relationship sideways, and from two different point of view, a romantic one and a philandering one. The issues are not taken straight on, they are viewed from afar, judged by indirect actions and their consequences.
The good. Well built, realistic, almost down to earth, and interesting story with lots of psychological details and some laughs. Excellent camera work and editing giving you a nice emotional perspective. Characters with depth. Perfect ending. Great panoramas. Solid acting.
The actors. Paul Giamatti is in one of his best role, suits him admirably. I can't judge Thomas Haden Church, because I don't know him enough, but his performance was right on the dot. Virginia Madsen is great as the understated perfect chance. My favorite of the bunch, though, is Sandra Oh who serves us another one of her great interpretation, this time with a flair for very hot yet realistic sexiness.
The bad. The neurotic behavior and a few extreme reactions to some events can get a bit much at time.
The ugly. Nothing.
The result. Everyone should see this. Perfect for those who are not looking for romance, but a relationship. You'll smile, you'll frown, you'll shake you head, but you'll appreciate.
