What's eating Gilbert Grape

I dont know what I saw in the movie, it was complex. Simplest character was of Arnie's as he was flowing like a mad river here and there. But in a great control. May be Leonardo was actually talented boy at that time as well. But surely  Johnny's character was even more complex that why he let things away always from his hands. Lack of authoritative hand. He acted in the character brilliantly. Johnny was the central character, whose affinity towards his brother and family was very well shown in the movie. But strength in his role came after when  Becky ( Juliette Lewis ) came into different frames. Which let him think little about himself. That was the interesting part for the change which was coming into his character.
Sometimes I surprised that what sort of societies are they, which creates a different origin for writers who dealt with such stories and imagine such characters.
During the play sometimes I thought that I should not complete the movie because a sad yet happy ending was expected but not like this. In India it is almost impossible to fabricate characters and stories on such dimentions.
And also it depends if people are going to like such movies or not, which is a subject of great debate. Because in our part of society when does it happen like this?

I would surely be able to say one can watch this movie but not if not so then he had not miss anything.
