Yeah, it's a massive why would you even want to do that? for me. Even the dude that was sewing half a dog onto an actual dog wound up advancing medical science in some way, so he wasn't entirely a nutbag. But I do want to poke a hole in Doctor Evil Crazy McScience's premise of creating a whole new organism with the 'pede, as he's not really doing that. The three people in the first section are still individuals. So this is more like...forced commenalism, where they have to cooperate in order to assure mutal survival.

I said this to Nome on Twitter, this movie is basically the very definition of WHAT HAS BEEN SEEN CANNOT BE UNSEEN.
