Actually I like this more than Summer Storm (possible Spoilers)
After seeing both movies I felt that Boys was much more interesting for me. I guess I'm a tad biased as I did track and field during my high school days and could relate to it more.
The lead character Sieger came off as much more likeable and less homophobic than Tobi from Summerstorm. I mean all Sieger did was shove Marc (no one needed to put themselves in a sling). Boys also had a much better ending.
Granted the two films were quite different. Summer Storm was more about the friendship between two close friend and unrequited love. Boys was less about a close friendship (which wasn't that explored in the film though the best friend appears to know all along what team Sieger played for) and more about discovering oneself and finding love in an unlikely place.
Both films were good I just felt Summerstorm was too over-hyped (and I was more interested in the relationship between Georg and Malte than the leads: Tobi and Achim)
