Some young motocross riders discover a large, abandoned military research site in the desert and come face to face with giant, mutated ants. Frankly it is ridiculous that such a place would be so easily accessible. Add to that cheap looking CGI, awful continuity and humour that is plain stupid, this is certainly not a good movie. The scriptwriter has obviously used the same dictionary as Wayne's World, Bill & Ted, Beavis & Butthead, etc, lines such as "Dude, you're not a squirrel, you're an ant!" quickly become tiresome.
However, there are a few factors that I found positive. The characters were quite likeable, despite the annoying "dude" overkill dialogue, and the acting was decent. To my surprise I discovered after watching that it was made in Europe, the European actors did a good job doing American accents (they are often painfully bad). The arid Spanish landscape served as a good stand-in for a desert in the US.
Apparently the film is based on a 1980's video game of the same name and during the closing credits plenty of game footage is shown, which I liked.
This is a bad movie, almost certainly the worst ant flick that I have ever seen but fortunately it does partly redeem itself, hence my 4/10. But there is no way that I could sit and watch it again.
