Questions about Life On Mars ending (and BTW I never expected to love it as much as I did. It was awesome!)
Okay so Maya was originally in danger when Sam went into the coma, and it's a big plot of the first episode that Sam manages to catch the serial killer in 1973, and change the future in that respect.
I was expecting Sam, back in 2006, to look into what happened with Maya. And to check out whether Gene Hunt and Annie ever existed. But if he did do so, they never let the audience in on it :/ I find it hard to believe that the entire 1973 world was all just in Sam's head, especially as some of the stuff he didn't seem aware of (like questioning is heroin a new drug for example). He wouldn't have known that much in-depth about 1973 to think up an entire world like that.
I saw it as Sam being in a coma, and actually being in 1973 for real at the same time. I'm not sure how that would work, but it's what makes the most sense to me... Although the episode where Sam is OD'ing, sees the case come together through the television, and finding out in the end that it really did happen that way, doesn't quite fit with that. Just because of the info that Sam didn't have (like the father being a photographer), so it's hard to see how he could have pictured the case being solved correcetly, unless the 1973 world was all in his head. I'm so confused!
I wondered if Sam had even woken up though, because it seemed a bit strange for him to just walk out of the hospital/go back to work, after having been in a coma for months, and going through brain surgery.
