Rats starts out promisingly enough, with a suicidal woman being admitted to a secure institution for psychological treatment, only to discover that the staff are hiding the fact that patients are mysteriously going missing; given the title of the film, it comes as no surprise to find that killer rats are to blame for the bizarre disappearances. What does comes as a bit of a surprise, however, are quite how awful the special effects are in this film, and how much they ruin the whole experience.
Director Tibor Takacs' is best known for his 1987 teen-friendly horror The Gate, which delivered plenty of fun chills and thrills and some pretty good effects, proving that the man knew how to construct a decent film. On Rats, however, I suspect that he caught a glimpse of his digital effects mid-shoot, and, on seeing how excruciatingly poor they were, just gave up trying (either that, or The Gate was a fluke).
The barely-above-video-game quality CGI rats are so unconvincingly combined with Takacs' live footage, that I actually felt embarrassed for all those involved with the film (especially Ron Perlman)a shame, because, had the effects been much better, this could have been quite an enjoyable piece of schlock horror: the cast don't do too badly with the hokey material, the cinematography is good, and there is a bit of welcome gore in the form of some gnawed carcasses and severed heads.
Since Rats, Tibor Takacs' has directed several other creature features (Ice Spiders, Mega Snake, Kraken: Tentacles of the Deep) all of which I have yet to check out; for his sake (and mine) I hope that the monsters in those movies are a tad more believable than his dreadfully shonky rodents.
3.5 out of 10, rounded up to 4 for IMDb.
