It's Man Problems. That's basically the easiest way for me to describe that story. The history of man problems from the Viking and Berserker experience.
Actually a really good movie. Beautiful soundtrack too, I love me some hurdy-gurdy.
I have never seen an American Spiderman movie so I couldn't really say. As far as the difference between it and the comic, the Japanese version leaned more to goofy Sci-Fi and standard characters like Mary Jane Watson didn't seem to exist.
