I remember watching this as a kid and it was bad, but saw it again recently and it was worse! It is a film featuring a monster within a lake that is barely seen, lots of talking within labs and a really old cast of unattractive leads that we have to watch two of them make out for what seems like more time than the creature is present on screen! Not a good film in the least, but it is entertaining in its presentation and I am surprised this one never got riffed on MST3K cause it features film whose length fits their time frame, was rated PG so not a lot of worry about cutting stuff out and it is a very bad movie!
The story has a guy dynamite fishing, who accidentally releases a strange creature in a lake. The movie is called bog, but a bog is generally like a swamp, but with less water. Well, this guy is killed and two couples come to this place to drink beer and fish. Well the guys did, the wives came along to complain. The monster gets them and we have a couple of older people trying to figure out what is killing people, a sheriff who keeps losing deputies and a monster that doesn't look that bad getting virtually no screen time.
The monster kills people, but you really see nothing of the attack. One of those films featuring implied monster attacks. The cast, as I have said, is old. When the two girls on bikes ride through it was a breath of fresh air that was not there long enough as they get attacked. There is a swamp hag who kind of mumbles her lines to the point you cannot understand her and a guy who resembles Torgo who promptly gets killed when he leaves her shelter even though he should have known they'd be safer waiting inside her place.
A lot of films were made during the 70's of the lower budget horror variety and some of them work. Shock Waves, Dawn of the Dead and countless others that were still really good. This one was one of the many that were just plain laughable in their execution. Why would any filmmaker think that anyone would want to see a couple of people old enough to be grandparents making out? Though, honestly, that is the most horrific scene within the movie...
