Love the characters and the show, but this Blu-ray collection is sub par. Killjoys dialog is fast-paced, off the cuff, and laced with SF technical jargon, This collection, like Season 4 before it, comes without closed captioning of any kind. I watched it all, but don't quiz me on the finer points of what happened. I couldn't sort it out. We all know SyFy can do better. Looks as though the Prime streaming version is captioned, so WHY not the discs?
