As noted by others: no gay film in the actual sense, rather a mixture of surf film, teen movie, growing up story, with a little family drama, a little working-class drama, some gay issues, but especially a film about two (or three) brothers. Therein lies the weakness of the film: it wants too much and gets lost. If it focused only on the brothers and the gay issue, it would surely have been more successful. I don't think the film is a great achievement, but mainly due to the two outstanding characters of Fergus (Xavier Samuel) and the / his grandfather (Barry Otto) it is pleasant and entertaining enough and at the end -with the talk of the twins on the beach about the third brother- it comes full circle. But still: more focus on Fergus and his relationships with family and friends instead of Jesse and his surfing and the beach parties etc. would have certainly worked better and would have been better received by the audience targeted by marketing.
