Legit teared up during that ending scene in the Rectify season opener. They keep nailing all these scenes you expect to be really sappy cheese. The only other show that comes to mind, where it's just all Heart are the really great eps of Friday Night Lights.
Rectify and FNL share a lot of DNA despite being in somewhat different TV eras (with a little overlap, as FNL ended in 2011). While most shows are concerned with dark anti-hero drama (BB, GoT, Walking Dead, Mad Men, et. al.), Rectify is a wholly optimistic and positive show about a man coming to life again after being imprisoned for so long. It's like a darker Enlightened.
And you're right, that final scene was magical. One of the few times a dream sequence has been elegant.
