As a jungle movie, well, they barely spend any time there (and the piranha, unseen, only have one short "appearance".) As a movie, it's one of those things where nothing happens at all for the first hour and by the time whatever does happen comes around, you just don't care.
It's the third annual JUNGLE JUNE! When I watch mostly jungle movies that I haven't already seen. Unfortunately, at least five of the ones I was going to watch on OK.RU were removed during a mass video purge the other day. Anyway, first up we got the "stark realism" of JAWS OF THE JUNGLE. It's what it is...a somewhat faked "documentary" with vampire bats as the reason for the tribe's need to move to another place, which is the plot. Nothing too special, it's over before you know it.
