Bite had potential - woman gets bitten by bug, then slowly begins to turn into one, but it fails to deliver. The writing is nothing special, the acting mediocre at best and characters make head-scratching decisions.
The film also relies too much on the slime and aqua beads, making it seem whatever Casey is turning it more Aquatic than insectoid.
Casey discovers a large, bad and weeping insect bite and decides not to go to hospital, instead she rings her GP and waits for a call back. She has no concept of wound care, dabbing ointment on a bite that's basically a hole in her leg, before scrubbing it with a cloth.
Her fiancée gets unwittingly infected and pees blood, but doesn't seem overly concerned about this. He finds out she slept with someone else at the bachelorette party and then immediately decides to screw the friend who brought him the bad news. My fiancée and I were practically shouting at the screen over these weird decisions.
By the end Casey's apartment was covered in eggs (like aqua beads) and what looked like cobwebs (she wasn't turning into a spider) which only added to the confusion.
All in all I don't think I'd recommend this film. I saw it on a list of horror films that were difficult to watch (supposedly due to its grossness), but if you're a seasoned horror fan, like me, Bite will no doubt dissapoint and confuse rather than gross you out to the point of switching it off.
