Jim's Superpowers

Yes he does have an uncanny ability to outwit professional soldiers.

Thinking about it that was a bit silly, he suddenly turned into Jason Bourne/James Bond for the last 20 mins of the film.

lol..

You're an IDIOT! He didn't have super powers. All along when he woke up out of the coma he was helped along in this new world. Remember MORON, he didn't live through the plague, he woke up after the fact where other survivors adapted, he never had that chance. He had courage and guts to survive all along but he just didn't know it until faced with the fact that this would be the end of the line unless he acted and he did. It was about going all balls out to survive and he chose that option.

They came from within. They were always there to begin with.

But it took seeing the monsters that the soldiers had become toward the women, and nearly being executed himself, to unleash it.

We should be clear as to exactly what was unleashed, though. Don't overestimate or overstate exactly what he accomplishes there at the end. Jim became a reckless crazy man. He just blazed through the camp like a whirling dervish. He did not become a super-ninja or spec ops one-man army. He crazily threw all caution to the wind and dashed through their defenses because he had run out of options. His back was pushed tightly against the wall, and he decided that he was mad as hell and he wasn't gonna take it anymore.

And then he got himself shot, for his troubles.

We could all do that, more or less. It's just that some of us would end up accomplishing the getting-shot part a little earlier than others...

If you have to ask this question, then you have missed the main driving point of this film. Although to be fair, I cannot blame you.

A rational person would look at this situation as ask the questions you have asked, but only a small amount of the population have truly been in a fight for survival. Those of us that have, understand the juxtaposition of both losing control and mastering it, in a single instance to defend ourselves, or the ones we love. The strength, speed and focus which accompanies these moments are unparalleled by anything you could imagine feeling in life. While military and fighting experience go a long way, unless it is coupled with this will to survive, it basically means nothing in comparison.

I cannot recall a movie that has so brilliantly and terrifyingly portrayed this raw, primal instinct. It's an ugly, brutal ending and it is perfect in conveying what it is trying to tell.

Yeah I thought so too. The first part of the movie was great, but with the death of Hannah's father logic seems to vanish.
I spend the second half of the film with my my mouth open in disbelief that I hurt my jaw. After the ending I banged my head on the wall and went to hospital to get treatment. I'm OK now.

It was a bit of a silly Hollywood-y scene, but not that unrealistic. I got the sense that two things made Jim really switch - the first when the soldier said he wanted to rape 'the black one ... and make her squeal' (you saw his entire attitude and stance change after he got up off the ground) and the second when he saw the plane in the sky, and realised what the other man had said was true - the rest of the world was still out there, there was a future worth fighting for. In the end, he planned it well - that's all. He didn't even engage in that much hand-to-hand combat - he let the infected do a lot of that for him, up until the end, when he was faced with the man he REALLY hated.

I wish he had been wearing a shirt or something, the nudity felt a bit ridiculous.

As for the bit with the kid? Whacking a kid with a baseball bat? We could probably all do it, if we had to. It took him a moment to muster up the courage, too - standard Jim.

Adrenaline does crazy things to a person. As do terror and a sense of self-preservation. And never underestimate the element of surprise. These people were on watch for creatures that growled and snarled and ran recklessly straight ahead, not some guy sneaking around and popping up unexpectedly.

Also, Jim was a bicycle courier. Not exactly hard labor, granted, but it still requires more stamina and fitness than, say, your average retail or office job. He would have been in shape. Certainly in better shape (generally speaking) than somebody whose profession kept them behind a desk all day.
