I find the topic a bit too subjective, I mean everyone has different tastes in movies. I enjoyed Star Wars: A New Hope (the original) so much, I've seen it more than 130 times, but I can't stand Star Trek: the Motion picture. I've met people who think the exact opposite way, and also people who think that Jim Carrey is brilliant in everything he stars in. I think Jim Carrey was a lot funnier when he was only trying to be zany, and not doing the stories "with a message".
That being said, I think David Lynch's Dune really kicked ass. Still have to see the newer one.
