This little gem was pretty interesting. If the "sinkhole" in the story isn't real, then the special effects are really impressive because it looked like the actual gates of Hell. I remember the actor who plays the salesman, Jason Harris, from TV. He was the host of a Nickelodon show a few years back called "Double Dare 2000" or something like that. It was cool when I recognized him and my daughter whose 13 recognized him too. He did a good job of not "taking it over the top" like he did when he was hosting the kids' show--in fact, I like him better as a dramatic actor. Even though this is low budget, the directing and cinematography were good too. Great exterior shots of the aforementioned sinkhole with nefarious steam rising from it, as well as some cave-like interiors with nice lighting and shadows. I think this was filmed somewhere on the East Coast. According to the IMDb page, Sinkhole has won some well-deserved awards so I'd say it's worth a watch.
