Query: What it had to be.

This film was simply what it had to be. It was the final piece of the puzzle and as such, is worth adding to your collection. Far superior to episodes I & II, this movie provides a type of closure. We now know the origin of Vader's illness, and relationship to the Sith master. We also are given the circumstances of his turn from good to evil as well as a background to why the force is so strong in Skywalker.The movie has a nice pace and feel, and keeps your attention with better than average acting and as always, superior effects. The one major positive of this movie is the ill-concieved immaturity of Annakin has dissipated. This allows one to actually enjoy the film without being distracted by the man child's crying over perpetually spilled milk. The story could have been made a bit clearer, and the dialouge a bit crisper, but in all this is a worthy addition to the Star Wars family.
