Paul Giamatti and Alex Shaffer in Win WinWIN WIN

When I say that writer/director Tom McCarthy's Win Win could easily serve as the inspiration for a long-running TV series, I don't mean it in any way insultingly, partly because our current small-screen options are, in general, vastly superior to our big-screen ones. Mostly, though, it's because this serious-minded comedy is so teeming with nuanced, empathetic characters and complicated yet wholly plausible situations and circumstances that you want to luxuriate in Win Win's universe for far longer than the movie's too-brief 100 minutes - like, for an hour a week over several seasons.
