I don't know about anyone else, but to me, the timing in this film was very confusing. According to Celestia, the portal would be closed and wouldn't be opened again for thirty moons. So, how long is thirty moons? Thirty nights? Thirty weeks? I think this was explained in "Apple Family Reunion," but I could be wrong. Also, it seems that the hours in a day are the same as ours, that is twenty-four hours. Additionally, when Twilight does get to the human world, we learn that Sunset Shimmer has won the crown for the past three times in a row. Again, this is where the timing gets confusing. Exactly how much time has passed since Sunset Shimmer went through the mirror and when Twilight did the same? I don't recall this ever being explained in the film. I understand that this is a kids' film and they can't take the time to explain everything. they do have a time limit and kids generally do not have a long attention span. But that was just one thing that really hindered me from enjoying this film because I was trying to figure out the timing of events throughout the film.
