To Leslie is an acting showcase for Andrea Riseborough, playing an alcoholic Texas woman who abandons a child and blows her entire lottery win. (as well as any man who will look her direction) Also a notable supporting performance from Marc Maron, mostly known as a comedian and podcaster, who plays a motel manager who tries to give her a break and help her get her shit together. Many themes which would be trite and dull in lesser hands, are rendered with depth and beauty here. As Hairy said, Riseborough brings some subtlety to her rendering of a drunk and some predictable trajectories.
Also, not technically a movie, but its length and standalone plot should qualify it as one, is Beyond the Sea, one of the episodes of Black Mirror s new sixth season. (not to be confused with a Bobby Darin biopic). It is brilliant, with fine performances from Aaron Paul, Kate Mara, and Josh Hartnett, and I would nominate it for any Best SciFi Drama of the Year list. The other two episodes I had seen had me worried the whole season would be nothing but Black Mirror Lite, but Beyond the Sea definitely brought it back to its full darkness and depth.
