Grease was cute. And Olivia Newton John could sing! But not John Travolta.
Star Wars was cool, great special effects for the time, but Tron was better.
Star Wars Empire Strikes Back was better. Episode I and II, I felt were more "divided" trying to tell an adult story, but keep kids happy (with Jar Jar Binks and the kid) at the same time. But the rise the Emperor was the part I like from Ep. 1 and 2.
