Hmmm. I watched this again recently hoping that it wasn't as mediocre as I had thought first time around. Sadly, not. The opening scenes are great: a good fight with lots of action and lightsabres; then it descends into a sort of cross between "Ben Hur" and "The Golden Child" with some pantomime thrown in too. The film is clearly designed to be part one of another trilogy and as such spends way too much of it's time setting the scenes and establishing the characters for the films to follow. We do start to get a sense of the evil "Palpatine" and it looks spectacular, but it is basically pretty empty and soulless with a very weak storyline.
