Signs of bad: 1. Cover is more scary than the what's in the movie. Called false advertising. 2. Usual no-name studio, "Chiller Films". Usual no-name $100/day actors (OK, a few TV spots and similar cheap-to-make movies for their credits.) 3. Usual dumbed down stereotypic plot hooks: Teens in car going to a remote site to party, with lots of boring scenes of van driving on road. 4. Usual teen mix of hot chicks, jock, nerd/geek, cool quiet type guy. 5. Usual stranded setup with no cell reception (so overused there are actual web sites that list all the no-cell-reception movies). 6. Usual alcohol, usual dumb decisions, usual tension amongst are doomed group. 7. So they get boat stranded on some small lake/reservoir. Only stranded in the sense that they can't figure out how to paddle a hundred yards to shore. 8. Monster is one, and only one (reproduction is not in the cards) large catfish (they actually do get that big) with eyes on the top of it's head (why during their many chances our dummies didn't poke them out is beyond me). Eyes should have been on the side for a scavenging bottom feeder. Anyway, it's scary attribute are some teeth that are functionally pointless except for snagging on sunken trees. 9. No scary or gory scenes except for a minimal amount of prosthetic blood tossed around.
