Some excellent body horror in this one. The villains had understandable if misguided intentions to save the planet, which has been corrupted by the influence of the Krynoids. I audibly gasped when Lucie was revealed to be working for that rockstar/ environmentalist guy (I've already forgotten his name and the name of the organization he works for) but of course she was just undercover. I felt as if I could smell the lush plant matter of the titular Hothouse.
