Though the film is up there with Manos in sheer, unfettered badness, it only makes the send-up by Mike and the Bots that much more enjoyable. The writer of the original film apparently forgot to make his anti-hero protagonists have some kind of redeeming characteristics.
As a result, we don't care what happens to them. The original film is also a collection of what they told you not to do in film school: it's badly shot, the scenes drag on because the editing isn't fast enough and there's no dramatic action in them, the audio isn't recorded well, and just about the only thing cinematically interesting is the devastated landscape of New Mexico.
Though the film is designed to be a "war film", it doesn't feel like much of one due to the limited budget. When your raiding force consists of 6 extras, expect Mike and the Bots to laugh uproariously.
The comedy dialogue by Mike and the Bots is hilarious. From pointing out the director/main actor's more-than-passing resemblance to Curly to turning into Carol Channing due to the bad power of the film, you'll be chuckling at this. This is up there with MANOS and Mitchell.
