My kingdom for a horse

Those who prefer their westerns with fewer shootouts and more Shakespearean sonnets will be thrilled by the long-anticipated "Deadwood: The Movie," with almost all of the original cast members back on board, including the magnificent Ian McShane. Traditionalists will suddenly feel the need for a John Wayne marathon.

The innocence project

"When They See Us" is riveting from the moment we meet the Central Park Five, the teenagers wrongly convicted for the assault of a New York City jogger. But the final installment of the four-part miniseries is nothing short of a masterpiece, thanks to director Ava DuVernay's unflinching eye for the details of prison life plus Emmy-worthy performances from Jharrel Jerome as the terrified but defiant Korey Wise and Niecy Nash as his soul-searching mother. This is DuVernay's greatest accomplishment — and that's saying something.

The concept of a spoiled socialite rediscovering herself through a Renaissance Festival would have been a terrific plot for a Katherine Heigl rom-com. But as the premise for the new series "American Princess," it's likely to run out of steam. Enjoy it while you can, especially the over-the-top performance from Lesley Ann Warren as a mother who sees the mud-covered fairgrounds as her own private hell.
