In Angel Gomez Hernandez’s Crawlers, a couple of gruesome set-pieces deliver a modest dose of creepy-crawly dumb fun – with emphasis on the dumb. Yeah, this is pretty silly stuff, with serious Snakes on a Plane vibes, except it’s “Spiders in an Apartment.” And while there is some genuine fun to be had with the spider-infested premise, everything else is pretty paper-thin. Character development? Barely there. Sensical plot details? In short very supply. Common sense? Apparently, nobody got the memo. Still, what makes this watchable is the sheer simplicity of the concept and the primal fear these eight-legged nightmares inspire. The visuals can get deliciously creepy and genuinely skin-crawling, with some nasty creature effects and plenty of opportunities for those little arachnids to pop up in places you'd really rather they didn't. There are moments of genuine suspense and a couple of the more gruesome encounters are particularly effective. Unfortunately, the characters are almost as irritating as the spiders themselves. The tenant connections feel wispy at best, most of the people involved are little more than familiar horror-movie stock types, and the increasingly ridiculous decisions they make are enough to test anyone's patience. And because there's so little character depth to latch onto, I never found myself particularly invested in who makes it out alive. Ultimately, Crawlers is the sort of movie that works best when you stop asking questions and just let the creepy-crawlies do their thing. It's not particularly smart, the characters aren't especially compelling, and the story is about as sturdy as a spiderweb in a windstorm. But if you can switch your brain off long enough, there's just enough spider-infused mayhem, nasty imagery and skin-crawling frights to make this a reasonably entertaining bit of B-movie horror. Just don't expect more than that.
