Yeah, me too. I always thought of the black clothes as a Jedi's outfit. I had never thought of him using the force choke being a bad thing, or any of the other powers he used being symbols of his slipping to the Dark Side. If they had had Yoda rebuke him for this in the movie like he does it the book, it would have really highlighted that point. Wow, reflecting on this now, that was actually a very brilliantly done slipping to the Dark Side. You have this totally selfless hero rescuing his friends, but using slightly questionable means of doing so. Imagine if Anakin had been that way, a true selfless hero. The most lovable and likable guy, and all along he is doing heroic acts, but as time goes on he throw a force choke in here, and some unethical mind tricks there. I think a really great depiction of a turn to the dark side, would be one where the audience hardly even notices, so subtle and so gradual.

The ROTJ Luke was always the coolest Luke to me when I was a kid, at Halloween I used to put on black sweats and one black glove and clip my silver metal flash light to my belt. I think I did that or about three years in a row. When I got a little bit older (10, 12, somewhere in there), I decided Empire Strikes Back Degobah Luke was slightly better than ROTJ Luke. I always wished I had some of those coveralls with the pockets everywhere.
