- Big-Lipped Alligator Moment: The inexplicable scene in which a doll comes to life and watches a spider land on its face.
- Narm: The climactic battle with The General. Where to begin? The fact that the spider somehow manages to tackle the hero onto his back MULTIPLE TIMES? The fact that the spider survives countless injuries, any one of which should've killed it? The fact that the hero rigs together a flamethrower to battle it and it still manages to thrash him? The way the spider clearly toys with him, leaving him pinned under debris and ascends his leg just so it can stare him down, eye to eye? The fact that, once defeated, it explodes kaijin-style? Or maybe the fact that the climax is simply a man with severe arachnophobia battling a spider in his basement, and the screenwriters used every contrivance in the book to make it dramatic.
- Nightmare Retardant: If you don't actually have arachnophobia, the movie can come off as remarkably dumb.
- Paranoia Fuel: You'll probably be checking every nook in your house for spiders after watching this. And make sure your tent is closed and well when out camping, so nothing can creep under your blanket...
- Retroactive Recognition: The animatronics technician that created the spiders for the film was Jamie Hyneman.
- Special Effect Failure: In the shower scene it's extremely obvious that the actress is wearing a fleshtone bodysuit as one shot is from above clearly showing the fastening at the back of her neck.
- Tear Jerker: Margaret's death. The fact that her last moment was speaking to a picture of her deceased husband, wishing he'd been at the party earlier in the day, before getting bitten.
YMMV / Arachnophobia
