Empire is probably the best of the oldest (read; best) Star Wars trilogy, due to it being the dark, dangerous point in the series. Full all it had an optimistic ending, Empire was the dark point in the series. The Rebellion was sorely challenged, and the heroes were beset by enemies they couldn't hope to beat, only survive.
