I have to admit, this movie truly did shock me. Within the first five minutes you'll feel totally engrossed by the plot. Most movies will lay it on you in bits and pieces , this one just hammers you immediately then leaves you wondering whats going to happen next.
The audio the video quality was outstanding for what looked like a lower budget film, but the full-screen only DVD bothered me. I'm guessing it was transfered this way because it was originally intended for TV. There was a double DVD released not long ago (Cabin by the Lake, Return to the Cabin by the lake) which can be found at Amazon.com and can also be rented at Blockbuster incase you are interested. (see link at bottom of review for direct Amazon page)
Overall , Judd Nelson does a fantastic job as the main role, the plot wasn't all that thick and sometimes was predictable, but always kept you wondering "Are they next?".
