This was a pretty cool movie for 1985. It even managed to be very "80s" without invoking all the shit 80s cliches that were getting old even back then.
Naw, that was a BARBARIAN from a crazy prehistoric world that came wandering in through a door that suddenly became a gateway to said world, to pick up their magical crystal skull.
You know, something far more sensible.
From a movie that had a zombie cowboy.
And a fucking human-sacrificing cult living inside their walls.
