It's not so much of liking that idea, but liking that scene in the movies. Yeah, it goes against the established mythos of the aliens, but it was still cool as hell to watch, and it really gave the movie that extra "umph" of brutality.
And let's face it, the only reason to watch that movie is to see the aliens brutally slaughter everyone, and then get killed by the predator.
The plot is pretty shit, the acting isn't stellar by any means, but the action (when visible) is nice and one sided. So many people get killed.
And so I liked this part because it was just one other moment where people in the theater were going "OH MY GOD!"
