I'll respond as I have some free time.
1. Maybe you guys try to read too much into this stuff, but I would guess that the mutant was only hoping his trap would work. I would also guess he chose Fred as he smelled Neville on it.
2. Already answered probably.
3. Yup.
4. Yes this entire scene is annoying. How he couldn't muster the strenght to limp is unknown. He couldn't have grabbed the rope, hanging unconcious like that for hours would leave anyone a bit stiff. He just barely got the blade on the rope, let alone his other hand.
5. As evidenced later when the woman and child show up and his almost violent reaction to a survivor colony, I would guess he was in a strong state of denial about alot of things. One of those(understandably) would be a refusal to attribute any sense of humanity to the mutants.
6. I thought the mutant was moving his ass, not being pulled. And yeah I'll give you this scene, probably so do the filmmakers, which is why it all becomes very fuzzy when those lights come on.
7. Deer once the human supply ran out, see the spooky early scene.
8. I do and don't.
9. ... I'd have to see it again. But it seems the theatrical version made more sense somehow.
10. That scene, in addition to the male obviously being pissed at the loss of his female earlier, which Neville dismissed, is evidence that there is at least an understanding between the mutants. I think Neville was expecting to be eaten personally.
