It's really too bad. This movie starts out great--a really quirky lead, an interesting foil as the (almost) romantic interest, and a really odd plot. And it's fine, right up to the point where it changes from a pretty good romantic comedy into an overly preachy climate change documentary wanna-be. The level of fatalism from that point on is totally excessive, and leads to major problems in consistency (e.g., the attitude of the hermit-like author to his son). And I'm about as far left as one gets on climate change; this preaching with Morse code using atomic detonations for the dots and dashes was really unneeded and fundamentally fatal to what could have been a solid film, and one with a strong eco-message.
