I watched the first 50 minutes of this, then I gave up. It was by and large unbearable. I have no problems with the basic premise, i.e. the son of a well-off family returns home for his summer holiday, brings a friend, the friend turns out to be gay, this causes the father of the family to confront his own feelings and his latent homosexuality. I buy it.
The biggest problem with this film, as I see it, is that even though (most of the time) I understand what it is that the filmmaker aim for - it's just very poorly executed. There isn't enough flesh on the bones for things to make sense. It's as if whoever wrote the script knows WHAT the characters need to do, but not WHY. For example, in one of the early scenes, the son of the family makes a big song and dance about how his friend should cover up when he's drying off after a swim. A few scenes later (after the friend has come out to him), the son questions why the friend is covering up (after a shower) when he's normally not shy. Rather than saying, "Because you told me to in no uncertain terms," it turns into an argument about whether the friend's coming out has changed things between them. And this is exactly my problem with this film: even though I understand why they argue and I think the question of what changes when someone comes out is valid, it's as if the filmmaker had to rush to explicitly make that point rather than allowing the audience to see for itself.
In this respect, the film is shallow. I don't see that whoever wrote it actually understands what the characters go through and why they act the way they do.
If you're not bothered about what motivates characters, then you might still get some enjoyment out of this film.
