A barrage indeed!
This was great to watch because you never knew what was going to happen next. The coolest thing was the animation and how amazingly slick everything was. I wasn't expecting there to be any dialogue at all, what a pleasant surprise! Another cool thing was how much I enjoyed it even though I did not see the original. You can simply never go wrong with stick violence. The use of color was flawless in this, everything just jumped out at you so much.
In fact, the only downside was that I wish this could have been longer. All the sound effects are extremely authentic as well. My favorite part is probably the scene where he throws that one guy in the venting shaft and he gets all chopped up. Killing can always be creative. The fast pacedness of it works so well.
