I don't know what to make of the title "Contamination .7" or "Troll 3." I saw this on video as "The Crawlers." There is nuclear contamination in the movie, but the figure ".7" and what it might mean was not mentioned (that I caught), and there are no trolls in the movie, but I haven't seen Troll or Troll 2, so I can't comment on what it might have in common with them.
The best thing about this was the cover of the video box. It has a pretty good illustration. Actually, the DeSoto was pretty nice too.
The movie starts dividing our attention between two young women on a bus. One gets stranded at a small gas station, while the other is returning to her small town home after having left it and her fiancé when she was in high school. For some time we keep cutting between the two of them, which is awkward.
Most of the acting was pretty poor, unfortunately. The Sheriff and his deputy, the nuclear plant's executives, goons, and whistleblower were are particularly bad. The threat in the movie is roots which have been contaminated by radioactive waste. They're now extremely long and carnivorous. What isn't clear is if they are just roots crawling around like worms, unconnected to anything, or if they are the roots of some tree or trees that are likewise mutated. We never see.
At one point, the townspeople show up to fight the roots. How that came to happen is not explained. Inexplicably, their solution is to find the barrels of nuclear waste that had been dumped in the forest and dig them up and put them in their trucks. They start to do this without any protective suits! Another solution is to bury the barrels under even more dirt, which doesn't make much sense either. Why the roots would stop attacking, or why they would die, when the barrels are carted away or further buried is entirely unclear.
The ending is particularly bad. It involves two horror clichés: the end that is not an end, and the freeze-frame.
