At the chewy, candy core of this assaulting, shrill, Skittles-hued headache is a well-meaning treatise on solidarity and female friendship. Ponies Twilight Sparkle, Applejack, Rainbow Dash, Pinkie Pie, Fluttershy and Rarity must pool their powers to save the kingdom of Equestria from all-encroaching evil and evil’s henchwoman, Tempest Shadow (Emily Blunt). Still, at least the all-star cast – including Taye Diggs as smooth-talking alleycat Capper and Orange Is the New Black’s Uzo Aduba as Queen of the Hippogriffs – seem to have fun. Music fans might also stifle a chuckle upon seeing the pop star Sia in pony form, nose-skimming fringe and all.
