I've gotten to see it too, thankfully.
I'll give it credit where it's due, it was used well for what it had, and that's fine. But something still doesn't set right with me. As someone that watched the originals on VCR til the tapes nearly broke, the light saber was a thing of beauty to me, and it was taken overboard with the prequels. For me, a very hardcore fan of the movies themselves, it takes only a slight deviation from the norm to be enough to snag my attention. I admit it does play into the character that possessed it, showing his one-up-man-ship nature, comparing himself to his idol, but I still feel it was too much.
I think that just having the blade's effect waver as it did was enough to set it apart, that aspect is honestly so damn cool, and it's sound effect also made it just different enough to get the point across: It's so darn cool. But.. .The extra hilt bits were this kind of.. Well my reaction to the trailer was basically instantly seeing the blade come out and I mentally went "Hey, that's cool.." and then the extras popped out the sides and then I suddenly blurted out a laugh. I'm not sure if that's what they were going for but that's how it went.
