The star is the world's nicest dentist, and the man making the movie played the dentist's kid in the movie. They go to conventions and screenings and they all seem to be quite in on the joke, reciting their horrible lines and cracking up the whole time. But then the director and his wife, who wrote the movie, fly over from Italy and has no idea why everyone thinks his masterpiece is so horrible. It's a fascinating film.
Now that we've seen it, we want to watch the Rifftrax version of "Troll 2," because there's no way I could see it without some sarcastic commentary.
By the way, "Troll 2" was not the sequel to "Troll," and it doesn't have any trolls in it, just goblins. And, well, that's not the weirdest thing about it. I suspect we all made better movies than this when we were eight and had a Fisher-Price movie camera and the cast was our cousins and random neighborhood dogs.
