i think it was a fitting end, i am glad they chose someone who appeared from the 1st season to be red john. tho i think the real intention was for it to be timothy carter from the end of the third series but as someone said it was all down to money and the network wanting to keep ratings up,

all in all i am happy with  the conclusion and to all the people who still dont think its actually over it is the rest of the series continues 2 years in the future and has moved on from the red john events, and to be honest who really wants the red john story to continue it has been 6 seasons now it needed to be wrapped up and not dragged on any longer

i just hope this doesnt cause the series to be cancelled any time soon

all in all i have enjoyed the ride and am overall happy with the conclusion tho for me i wanted red john to be bob kirkland i enjoyed how his character was played
