It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

All of these films share one commonality, that being a kind of emotional center that humanizes a cast of monsters.
