A magnificent but troubled heroine finally gets her ending in ‘Happy Valley’

If you’re a fan of “Happy Valley,” its hero, police Sgt. It’s hard to call it a happy ending, but happiness seems like an overreach anyway for someone as roiled by guilt and regret as Catherine. But contentment seems within reach and that’s a more realistic goal for this show’s magnificent but troubled heroine. All three seasons of “Happy Valley” are streaming on Acorn TV and AMC Plus, with the finale debuting on Monday. Unfortunately, unlike “Happy Valley,” there won’t be a third season of “Gentleman Jack,” not unless a streamer saves the day.
