All of these films you listed, I have watched. I've forgotten what the plot is in all of them.

Human Centipede (Last Sequence)

I mean, I enjoyed the both first movies, but this one is just dreadfully boring and annoying. Dieter Lasers permanent over the top screaming blowed my head off. And even Bree Olson, though quite a hottie, didn't help to get through the almost two hours of this movie. Pure definition of torture porn. But with me being the tortured.

Ah, there was this movie I watched. Can't remember the name, but it had something to do with aliens invading and taking over Earth. They would make people eat something that would change their DNA or something and they would make women give birth to human steaks. That's not the bad part, though. The bad part (well, one of them) was that I didn't realize the majority of the movie was watching (and listening) to people puke in a bucket. Although, to break-up the monotony, they did have one guy have diarrhea instead. Surprisingly, Christopher Lee, did a little narration in the very beginning and, Edward Noory, had a brief bit with his radio show.
