Dune 1984 had a lot of faults, that's true. It's been ages since I've seen it so my memory is hazy on a lot of it. I do vividly recall the duel between Paul and Feyd at the end though, Sting absolutely knocked his performance out of the park. When I look back on that scene now it feels like a great example of cheesy lines delivered with absolute, unashamed sincerity.
