Dull and predictable. That's about all I can say about Frogs. This man vs. nature drama is about as scary as a litter of baby kittens. Even the presence of Sam Elliott and Joan Van Ark cannot save this tepid nature film. I've seen more thrills on Animal Planet. The plot is predictable. The actors spout endless lines of meaningless dialogue. The scenes where the animals attack the humans are anything but frightening. The only reason why I didn't give this one a Bad rating is because the cinematography is fairly decent even though the special effects suck. Just skip this one. If you're looking for the best man vs. nature flick, Jaws will fit the bill quite nicely.
