MAY INCLUDE SPOILER TO THE MOVIE!!
After I just saw the movie, I can say that it was no “last hurrah” to the mane 6. It never even really included discord, starlight, flurry heart or any of the new characters. I did however spot discord as well as starlight in the end credits. This movie was a wonderful experience and I highly recommend watching it. It does expand the universe of the show by exploring places such as where the “hypogriffs” (water ponies) live, a place called “the badlands” and much more. I do believe that in the next season they with wrap up the series with the mane 6 allowing starlight and the other “in training” characters to step in and take their place. I don’t think that the mane 6 will leave the show but be more of secondary characters from that point on like celestia and Luna are right now. I hope for a lot from this show in terms of continuing other characters’ development such as the cutiemark crusaders because I think the mane 6 are very well developed at this point and will start to be overused if they have anymore time in the spotlight. I hope for a lot more and have big expectations for this series to continue on strong, implementing the new events that occurred in the movie.
