Yeah, exactly. The only difference in "What's eating Gilbert Grape" is that it had a wider emotional scope. You really feel for Gilbert because of the "choice-dilemma" he is in. One keeps on asking oneself (while watching the movie) "What would I have done if I were Gilbert?" And the hard part of the story is that there are no easy choices for Gilbert. To tell you more would be like giving the rest of the story away. My advise is to give the film a chance. You should be able to find it in any good rental store.

What's Eating Gilbert Grape
Originally released: 1993

Back when Lasse Hallstrom was good, he made this attractive and convincing portrait of the lives of an offbeat American family. Perhaps coming from Sweden, Hallstrom had the ability to see Americans as they couldn’t see themselves. Depp and DiCaprio are misfit brothers whose mother is so fat she hasn't left the house for years. Depp spends all his time caring for his family, especially his younger brother (DiCaprio gives an amazing performance as this mentally-disturbed boy) until he meets Lewis, the equally offbeat new girl in town. Lighter than Bergman, but not as gooey as Chocolat.
