I think by the looks of the trailer is going to be Perfect , the cast, the whole setting and the vintage look the film has
For me Henry ended up looking too old, though. They had a good base on him, but letting his beard show aged him too badly. Yes, I know some 14-15 years olds have beards, but I think it would be a nice touch to emphasize his youth (he is just a kid, after all) by making sure no beard is seen at all. I would even suggest armpit hair removal or trimming (again, I know at 14 some or many boys already have body hair, but not all, and not so much). He did a good job with his acting, going from shy to bold, but I saw an 18 year old guy, not a young kid. The same goes for Shannon.
But I did like the movie. And I felt bad for the poor cow in the well.
