Managed to catch this at a local indy theater, having been a Troll 2 fan for ages. I was fully expecting Best Worst Movie to be funny and entertaining -- which it was -- but what caught me off guard is just how touching and effecting it is. While the proceedings are constantly enlivened by George Hardy, the actor who played the father in Troll 2, many of the other actors lives have not gone so well. There's the sadly comic shopkeeper, who was on leave from a mental institute at the time Troll 2 was filmed, and the twilight years of the actor who played Uncle Seth. But seeing the actress who played the mother from the movie is downright unsettling , even tragic.
On the flip side, seeing the director and writers of Troll 2, and witnessing their fervent belief that they made an insightful, important film that was simply ahead of its time... it's like an Italian knockoff of Ed Wood, only less friendly. And while Fergasso comes off as a buffoon much of the time, there are moments where you really see how truly and honestly he believes in his films -- whether that is for better or worse is another issue entirely.
All of that, plus investigating the cult that has sprung up around this fantastically bad movie... I really have to say, Best Worst Movie is a genuinely very good film, far better than anything springing from Troll 2 has any real right to be. Highly recommended.
