I still would have liked to have anakin pull his lightsaber against the little kids....then the camera slowly backing away from him, then the door closing, then you hear the sounds of kids screaming/lightsaber swinging....I know that's cold, but would have made that evil seen MUCH more emotional
Yes, that would have definitely been more emotional. But the thing is it's not George Lucas' style. He doesn't want things dark (he fought a lot with the guys who were making TESB because he didn't want it so dark). That's also why he didn't want to kill off Han Solo in ROTJ, and why ROTS was a lot tamer than it could have been.
I thought of another strong 3rd movie in a trilogy: The Good The Bad, and The Ugly!
