Let's face it, in a made-for-TV movie like LEGION OF FIRE: KILLER ANTS! (aka: MARABUNTA), it's all about the ants. The humans are either those who seek to stop the onslaught, or the hapless victims of the tiny horde.
First off, the CGI ants are so poorly realized -even by late 1990's standards- that it's difficult to watch them, let alone take them seriously. Weren't there some real ones crawling around somewhere? Even a few live ants scattered here and there throughout the movie would have been better than these pitiful cartoons!
The humans aren't much better. Poor Mitch Peleggi. How did he wind up in this wretched nonsense?
SOME UNINTENTIONAL HUMOR TO HELP DULL THE PAIN: #1- The couple that decides it would be a nifty idea to get pictures of each other standing on an anthill the size of Devil's Tower! #2- The cartoon ants carrying away cartoon body parts! #3- The sheriff, standing atop his car, fending off the CGI bugs with a fire extinguisher! #4- While one of the heroes drives his truck over rough terrain, the two in the back of the vehicle bounce around in ways that would easily cause massive head trauma and grievous bodily injury! Miraculously, they're unscathed!
This is the sort of omni-schlock that makes ordinary schlock bow its head as it passes by...
