The Jedi in the prequels were jerks. That makes RotJ even better: Luke tells the stuffy old monks to cram a sock in it then goes to rescue his dad. He never says the L-word, but you can tell he has found something to love in Vader, or at least he hopes to find something to love.

Kid barely knows his dad, dad beats on the kid, but kid is still devoted enough to turn dad around and together they overthrow the Empire. If that's not love--unshakeable devotion, seeing what someone could be rather than what they are, giving undeserved forgiveness--I don't know what is.

I think the Prequel Jedi were reprehensible for a lot of reasons, but Luke is a great guy, certainly more generous and noble than I think I would be in his shoes.
