I love it and have watched all seasons. I’ve even come up with a way for Jack to come back at the end of the series. My suggestion: they never found Jack’s body. He did get out some other way badly injured and with amnesia. He wandered and a some people took him in and helped him to heal. At the end of the series he either gets his memory back or the people he’s with find out who he is and take him to Elizabeth. Wow! What an ending. Daniel Lissing would only have to be a guest star for a week or two.
