Lord of the Rings is just an epic trilogy. One of the best trilogies out there ever imo. Godfather may be better, but LoTR is just too damn classy. About the guy who said Star Wars was one of the worst movies ever, you cant be serious. Star Wars is legendary (the first trilogy, i'm liking the newer movies but i reckon the earlier ones are just too damn good), very important movie, and for the time they've been made, the special effects are brilliant.
I liked Gladiator aswell. About the Matrix, i reckon the first one was the best of the lot, i liked Reloaded a bit more than Revolutions. The 3rd movie was just not what i was expecting, i mean, i'm not too fond of happy endings, but Neo dying spoilt the fun for me. Still, i enjoyed it a bit, especially the city of machines part.
For me the worst movies i've ever see are definitely Wild Wild West, Batman & Robin and Daredevil.
