This is a very low-key, character-driven, and chat-heavy little movie, but it's also surprisingly heartfelt, impressively insightful, and actually quite funny here and there. Writer/director James Ponsoldt has set out to make a '70s-style two-headed character study in which quiet conversations and gradual character arcs are the focal point, and thanks to a superb screenplay and two excellent leads, the kid turned out a really accomplished debut.
Nolte's at the top of his game playing a disillusioned old umpire named Ray Cook; Trevor Morgan capably holds his own as the naive teenager who (yep) learns some pretty valuable lessons from his temporary new pal. And when the movie delivers some bittersweet emotion punches in its third act, they're actually quite effective -- because we've grown to actually care about these two characters. (Timothy Hutton also gives a great supporting performance as the kid's mildly disturbed father.)
Just a simple little "people drama," nothing more, but a very well-crafted and heartfelt one all the same.
