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
Both Wil and Sheriff Jones looked like they came out directly from an old movie. They were really well done.
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.
