Although this is a "rite of passage" film about teenagers growing up , and their complex emotions as they find first love, it is so well crafted it will appeal to all age groups who appreciate a good film. Nearly everyone can identify with the emotions from some period in their own lives. Freddy Highmore's acting is superb and totally convincing ; its a step further towards adulthood from his fine performance in "Toast", and one can look forward hopefully to more films from one of the most talented of young British actors (not that I would know from his film accent that he was not American!). Emma Roberts is equally as good, as might be expected , and Blair Underwood convincing.
What differentiates this film from other similarly themed films is I think the quality of the acting, casting and production. Interestingly, Johnnie Depp was an early protagonist of Highmore's acting ability, and I can see a parallel with "What's eating Gilbert Grape" - with Johnnie Depp - which was an early example of Di Caprio's acting talent.
A great film, watch it!
