Actually, it was better than even the last Bruce Campbell-OSC effort.
The magma movie showed some promise, but no form-fitting clothes, or even a hint of skin from Amy Jo probably lost a lot of male viewers (the gratuitous camper in the tent scene was out of place, and doesn't count), the dialog was pretty ridiculous at times, and the preachy religious environmentalism of man=bad, planet=good deep sixed it.
