In the last few months...
Alexander -- utter pretentious cinematic crap from a once fine director whose brain has turned to mush due to his drug abuse. Makes you long to see "Showgirls" again or perhaps "Cocktail."
The Last Samurai -- Should have been called "Dances with Samurai." They took Dances with Wolves and replaced the indians with sword-welding sumarai and followed every plot point exactly.
The Butterfly Effect - Watching Ashton K. try to act is worse than sitting through another book study of the Revelation Climax book.
March of the Penguins -- Don't believe the hype. You'd barely watch this for free on Discovery Channel. Want to see an amazing documentary on nature? Watch "Deep Blue" instead.
