Shelob's Sting?

[Knight of Gondor]

When I saw the movie the first time (and I've only seen it once, but I hope to change that soon!) I couldn't figure out where she stung him. I think the ratings are kept lower if the actual penetration isn't shown, so it looked to me like the stinger went BELOW camera to sting him. I always thought he got stung on the chest/stomach, but the mithril changes that. Perhaps the lower stomach area? <P>If the poison attacks the brain, it could explain why Frodo had enough time to spend about three bajillion minutes standing there and grunting, gasping, and moaning and making faces like "What just happened? You know what? That HURT! I think....I think I need to lie..." (thump). I'm not being overly critical, but it just seemed too similar to the Expression of Pain as displayed by Frodo after the cave troll stabbing -- and way too prolonged.
