There are actually a lot of great scenes in that movie:
1. It was messed up because we have to add boring humans to everything.
2. It was sometimes messed up because of how fast shit went down, it was like Alien...flash of dreadlocks ...something happened. The movie was not as awful as people claimed it was, it was just like Freddy vs. Jason. WHAT THE FUCK DID YOU EXPECT FROM A MOVIE CALLED ALIEN VS PREDATOR?
I didn't expect much at all.. thats why i put (generally bad) in brackets. I just found that particular fight scene noteworthy but really nothing else.
