Creepy Crawlers is most definitely Elkayem's warm-up or practice film to do before Eight Legged Freaks was released two years later. The quirky, fun-spirited tone of Eight Legged Freaks is completely present in Creepy Crawlers, and it is heightened mostly by the acting and music. The situation still feels real and dangerous, and there are some really great gross-out and hilariously shocking moments here. The story moves fast, although it does go a little too fast at the end, when the climax comes too quickly and is not quite as satisfying as it should have been.
As a sidestory to the cockroach problem, there is also something going on with one particular man on the island, Jack Wald, who is angry with Cahill for buying his family home that was taken by the bank. He in turn has some friends that are behind him, and cause some extra shenanigans with Cahill, the sheriff, and Nell when they obviously have more pressing matters at hand. Instead of feeling out-of-place, though, this actually does add some extra conflict to the plot which otherwise might have been too easy to get out of - just get off the island.
Creepy Crawlers (I think the official title is actually They Nest but Creepy Crawlers is the DVD I got) is a wonderful little animals run amok movie with a great personality. The climax has a great setup, but it needed just a bit more tension to make it really explosive and satisfying. Otherwise, really fun movie! I loved it!
