The opening episode of “The Boys,” a wacko superhero series in which the “sups” are out-of-control, corporately manipulated villains, was a mixed bag for me but I was compelled to watch on. I’m delighted I did, for the remainder of the season’s first half is a sprightly confection, full of so many gasp-out-loud plot twists that I … gasped out loud. Ragtag heroes Billy Butcher and Hughie are joined by Frenchie (played with contrary delight by Tomer Capon) and Mother’s Milk (a sturdy performance from Laz Alonso). The villains continue to impress with their depravity. Splendidly scripted and directed, with bouncy dialogue that works, the series rushes at a fast clip towards a finale I cannot begin to imagine (our heroes are, after all, ranged against superheroes). Roll on, second half.
