Galaxy of Terror is insane as hell, and while it didn't work 100% for me, I had to admire how far it was willing to go.
The various kills that occur throughout the film were pretty outlandish. For example, in one scene, a female crew member battles a maggot that’s grown to an enormous size. Inexplicably, this huge, worm-like creature manages to wrestle every stitch of clothing off of her body, and then, before doing away with the poor girl, it rapes her (that’s right, folks…raped by a giant maggot). Galaxy of Terror contains a hodge-podge of gory kill sequences such as this, though I have to say not one of them matched up well with any of the others; they just kinda "happened", with no real explanation as to why.
For a low-budget movie, the special effects were quite good, and this, along with its impressive cast and gruesome kills, was enough to keep my interest. But with a story that doesn't make much sense, Galaxy of Terror was also a bit trying at times, and had me scratching my head more often than not.
