I bought this movie on blu-ray for $5 at Wal-mart and finally got around to watching it last weekend. Instead of making a new thread about it I figured I'd just post in this one.
I liked the movie very much, it really makes you think. Funny thing though, I can echo the sentiments of both the lovers and the haters in this thread. Did Chris act like a dick at times? Sure, he did. Did he make some stupid decisions? Hell yes. But he was also right about one thing, we all have a wanderlust inside us. Some more than others, many repress it or are scared of it, but it's in all humans inherently. And it can even be a healthy thing.
Chris's largest problem is that he took it to an extreme. Too much so. He could have done the same journey and not purposefully cut off all contact with his family. He could have made the same trek into the wilds of Alaska and let at least a few people know where he was and what he was doing. He took "loner" to so much of an extreme that in the end it killed him.
I've gone on camping trips into wilderness with very little packed. But I never needed to abandon my entire life, friends, or family to do so. And I always let someone know what I'm doing. I make it a point to go on at least two week long (many times longer) Harley cross country trips per year, where I usually camp every night and basically put my normal life on hold completely. Think Wild Hogs without the comedy and crashing. I am frugal in the sense that I don't buy needless things. Some would say I'm spartan in some regards. It doesn't mean I'm broke, it just means I'm not big on hoarding material things.
Chris went overboard in his lifestyle choice. On one hand I respect him and envy him, but on the other hand I think he's an idiot and super selfish in his actions.
Either way, it's a good character story whether you like it or not, and certainly worth watching at least once if just for the experience of it. A lot can be learned from his decisions, especially from his mistakes.
