I don't buy ANYTHING anymore (exception: I got GotG for my kid for Hanukkah), least of all TV series sets (I borrow them from the library all the time), and even I am tempted by that Arrow deal!
I've seen a few minutes of it here and there, and it does look good. I know some people who really love it. My wife would probably not be into it though. . .being into older, out-of-shape former HTF reviewers, and all. . .
