I think I was pretty out of it when I watched it, I don't remember either of those scenes. In fact I didn't even know Sean Bean was in it.
Thing is, I thought the overall concept (whatever it was, I forget) didn't quite make sense somehow and I think all through the film that idea was just lurking at the back of my mind making everything I saw slightly unsatisfactory, even the cool bits.
My friend did some of the fx on it though which is pretty cool I think.
