Out of 10:
Episode 1 - 5. Jar Jar Binks. Don't think I need to explain any more.
Episode 2 - 7. Picked up a bit, started to feel like it was fitting into place.
Episode 3 - 8. Easily the best of the prequels, dark so closer to Empire.
Episode 4 - 7. Too slow moving for me at times to get a higher score.
Episode 5 - 9. Brilliant. And then Vader comes out with his "I'm your father bit". (Does that need spoiler tags?! Surely not....)
Episode 6 - 8. Sort of went a bit Phantom Menacey with the silly creatures at the start, and the irritating mini wookies, but the space and lightsaber battles were really satisfying.
