It seems a lot of people are expecting some strict continuity. This is strange to me, as it is without precedent in MLP of the past. There were already multiple unrelated canons in G1. G3 does not connect to any of those. And G4 did not connect to anything before it. Is this a failure to communicate to the audience what this new generation is? And will this actually have much effect on how successful it is?
At least there was nothing insulting to any of the worthwhile parts of G4 in the film.
