I have always liked this movie. It has some genuinely creepy scenes, not to mention gore(one of the camper's is beheaded by the monster grizzly), and a vulnerable, perpetually "teetering-on-the-edge" heroic "good guy" character in the park ranger, played with the necessary(but not excessive) tension and consumption of cigarettes, by Christopher George(of the 60's series The Rat Patrol). This film lacks the grandeur of "Jaws" but is nonetheless, IMO, worth a look, if you are a fan of "giant rogue animal on the loose" cinema as I am. The movie was filmed in south Georgia. This film is available on all Region DVD and Region 1 DVD at Amazon.com.
Here's one link where the Mediablaster's 2 disc R1 DVD of this film is for sale: http://www.antonline.com/p_611-GP_366009.htm
