It's such a shame the finale was never made. It sounded amazing, and would've been cool to see the human Sunset Shimmer.
The Winter special wasn't a proper ending and hd no conclusion to the show whatsoever.
I was thinking it would could be cool if MLP: FIM got a second movie. Such as a prequel to the events of the final episode. Not sure shat the plot would be, though.
I miss FIM, and think it'd be cool to get a second mvoie.
