While I've been enjoying the show I wasn't intending to buy the DVD or Blu-Ray of Season 1 but reading this from the promotional blurb "15 ONE-HOUR EXTENDED EPISODES" means I definitely now intend to make the purchase. That's like 15 to 20 minutes extra of every episode which I'm most interested in viewing. Wonder if they'll have an extended Pilot episode (say 75 minutes from the extended about 60 minute episode we got to see).

"more than likely what you see on the CW website or app."

As I'm not from the U.S. what's the run-time of those extended CW website/app episodes?.
