I saw this movie late one night on a movie channel here in Canada. It has received some medicore reviews here, but I think the movie is slightly above average, all things considered.
Yes, it was a low budget movie and that's quite obvious. The beautiful scenery of the Canadian wilderness is breathtaking. The characters played by Haggerty, and his son were quite well-developed and believable. Haggerty and Weiss also have some great dialog on their trip back to civilization. Roberta Weiss looks great too, and that doesn't hurt.
You won't be able to find this one DVD yet, your only hope is to catch on TV one night, or find a used copy of the VHS.
