★★★ Dexter’s juggling so many balls, he should be in the circus. There’s his relationship with Luman, his efforts to corner Chase and he also has the kids and the ever-suspicious Quinn with whom to deal. And a surprise, of course. But with each series of this well-written show, more layers of Dexter are revealed, and he seems less like a detached serial killer and more like someone auditioning for Modern Family. R.B.
