Six films to watch this week

‘Supergirl’ brings attitude to the summer blockbuster; five stars for quietly mind-blowing family drama ‘Blue Heron’; Mads Mikkelsen succumbs to Beatlemania in ‘The Last Viking’; stunt bros age disgracefully in ‘Jackass: Best and Last’; Jodie Foster turns French sleuth in ‘A Private Life’; ‘Toy Story 5’ pits Jessie, Woody and Co against screen-based tech.
