Once more, a failed military experiment spawns an abomination. This time, a not-so-itchy-bitchy spider finds its way into the silent morgue of an L.A. hospital, and since then, the mutated creature keeps getting bigger and bigger. Now, it's up to an unproven hero, the neighbourhood's exterminator and bug expert, Alex Mathis, to enter into the spider's mind, and save the city--and perhaps, the world--from an ever-growing menace that threatens to level everything in its path. It's hairy. It's hungry. It's the mother of all spiders. Can Alex stop the eight-legged behemoth before the U.S. Army takes over? Written by Nick Riganas

User Reviews

Good effects, but tries too hard to be funny
5 November 2015 | by Leofwine_dracaSee all my reviews

BIG ASS SPIDER! is a giant spider comedy/horror spoof following in the tradition of other arachnid comedies like EIGHT-LEGGED FREAKS. This one's an unashamed B-movie, gently riffing on genre conventions while playing out exactly the same as you'd expect, although it's noticeably more comedic than something The Asylum would churn out.

It was the comedic nature of this film that I wasn't really a fan of. If the comedy had been a little less over the top and the performances a little less theatrical then I would have enjoyed it more, but as it stands this goes way over the top in its attempts to be goofy. The central exterminator duo are particularly testing and unfortunately dragged the entertainment value right down for me. They just didn't appeal and their jokes felt stale and repetitive.

It's a shame, as BIG ASS SPIDER! boasts some very impressive CGI effects, which are a lot better than in similar fare put out by the SyFy Channel or The Asylum. Plus, the excellent Korean monster flick THE HOST appears to have been an inspiration here, particularly in a set-piece sequence where the giant spider rampages in the park which plays out almost exactly the same as in that movie. It's the highlight of an otherwise mediocre outing.
