^Nope, I guess I'll give another synopsis of the same film.
A rescue mission goes awry after it's members begin being slaughtered by an extra-terrestrial being.
Not entirely a GP comment, but Six Flags posted a picture of Mr. Freeze and Sky Screamer at SFStL with this caption:
I'm probably over thinking this, but I don't think anyone will be free-falling 218 feet backwards at a Six Flags park any time soon unless they turn the trains back around on Mr. Freeze.
