I’d intended to review each of the four stories in this boxed set separately, but they all work seamlessly as four parts of a whole story. It’s basically Spearhead from Space for the 21st century, minus the Doctor. This description makes it sound derivative, but it’s a good listen. The story moves at a breakneck pace and there’s lots of action. The dialogue is tense and terse but not as shouty as some of these high-octane Who stories can be. I cringed at the description of the plastification—lots of tiny little needles, ew—and cheered at Osgood’s various technological exploits. The ending of this story was quite interesting; it could make a neat sequel. I’d recommend this if you are looking to try out a UNIT story. ( )
