When a local begins fishing with dynamite in Bog Lake, something a bit larger pops to the surface: a green, bug-eyed mutant monster awakened from a long sleep, which promptly begins killing and eating fishermen who stumble across its lair. When biologist Ginny Glenn discovers the creature's evolutionary nature, the local sheriff decides to use most methods to destroy the tenacious beast. Written by Ørnås

Look, look! Hey, look over there! Look!
29 August 1999 | by (Chicago, lllinois, USA) – See all my reviews

There must be many different ways to look at BOG. I, however, can't find any of them. One has to wonder why the creators of this cinematic gem never chose to insert a "The" before the title, why an actress obviously plays two parts, or why the titular "bog" in question is actually a lake. Possibly the only defining moments in this film can be seen during the preview. Pay special attention to the cop who, completely off-cue, screams out "Look, look! Hey, look over there! Look!" Now there's some classic dialogue.
