I believe that the film was a very good try. I don't agree with most of the rest of the comments.
Its not a bad,usual film for teenagers like one said. Characters are nice, sympathetic and quite all of the actors play good their role. You never get bored. It has a lot of funny moments and a lot of useful meanings for youngsters and older people. It is a fresh and nice film which takes place in beautiful Santorini.
The 3 high-school boys go to Santorini searching for a chance to leave back their ordinary life and philosophize about life. It's a real tribute to a young person's world of emotions and not only. Many times, it reminded me my teenager period. It's so moving! The direction is also very good and the filming of natural beauties excellent.
Although the plot could be more tight and specific, the actors play very good for their age and for their role, and they keep you interested from the beginning to the end of the film. Not because it takes place to an island of my country, but i honestly believe that 5,5 is not a fair vote for this film.
