I watched the last two episodes tonight. This has the feel of a Stephen King ending or an ending from the Twilight Zone. Hard to say much more in case others have not yet seen the last two episodes.
Yes there are some unsolved questions but I guess if you go with Stephen King ending or an ending from the Twilight Zone, then it is over.
I did find this on the internet:

Personally with the ratings and the moving around I doubt if it will be back next year.
I could be wrong.
