I would say the worst was "Apocalypse Now" except for the air cav assault at the beginning.
I would also nominate "Starwars: The Attack of the Clones". Surely one of the most tedious, boring films ever made.
Oh come on! THat scene with yoda in the light sabre fight was quite humorous! I nearly fell out of my seat laughing.
I strongly disagree with your assessment of Star Wars: Attack of the Clones.
The movie is brilliant and the combat scenes are breathtaking.
The battle between the Jedi allied with the Clonetroopers against the battle droids and the seperatists is one of the most intense I have ever seen.
Yoda puts in the performance of his career in this movie.
