Seen all of them, Sam. A bit ridiculous at times, but quite fast paced and thoroughly enjoyable as nearly all the characters have their own stories to tell. John Voight absolutely steals every scene he's in, too.

That's what i meant by "A bit ridiculous, at times" Douglas. Wish i had his healing powers. That said, i can think of one human being who defied medical logic in speed of recovery from broken bones and bruised bodies. Sir Anthony McCoy. Maybe the writers were thinking of the former greatest jockey when they penned the Ray Donovan character :-)
