The original ending of Leon would have fit better with the revenge theme, Mathilda was doing everything she did to get revenge for her brother. She was supposed to run to Leon's aid and hand Stansfield the grenade pin.
I'm glad for the uncut version anyway, without it Mathilda seems more of an helpless innocent bystander instead of the main driving force.
Talking about blind vengeance, I watched Dredd last night, didn't like it. Probably my fault for watching it after 6 weeks of only seeing top 50 movies, but there wasn't a single likeable character in the whole movie. Maybe it's better in 3D with the sound cranked up. I watched it at night and had to put the subtitles on as the dialogue was whispered from the center speaker while music was blaring from the surround speakers.
