This movie is more like Corpse Grinders 2 than Astro-Zombies. And wouldn't you know it, both movies have the same star. So 2 different types of aliens come to Earth and create robot zombies to take over. Even though they have the technology to get here, their weapon of choice is a machete. There is literally 30 minutes of people grabbing their necks and zombies sharpening machetes. Then there's a 3rd type of alien. Minus 5 stars.
