[The] doc offers fittingly low-tech amusement throughout --which is a hell of a lot more than can be said about the tediously incomprehensible movie it champions.

Troll 2 has become a midnight favorite, and Stephenson looks at the phenomenon while catching up with his profoundly untalented costars and the grouchy Italian director.

A documentary so enthusiastic, good-natured and sweet about such an abject disaster that it almost makes Troll 2 worthwhile.

Not just an engaging chronicling of cult-classic movies, as it also makes for a fascinating deep dive into the psyches of those involved.
