My Little Pony's current iteration has been a strange if not fascinating family friendly product, and their movie continues this trend. Make no mistake, this movie is definitely written mainly with children in mind but with enough thoughtfulness that adults should be able to adequately enjoy it to at least a modest degree.
The songs are catchy and worth remembering, and the characters are distinct enough to be memorable. Although the main seven characters are not equally distributed in terms of screen time, they still get enough screen time to remember who they are for even a new watcher.
The movie is mainly straight forward with very few twists, but it makes up for it with strong writing. The pacing can be a bit too fast at a couple of points, but only just so.
Unlike most current Disney movies, however, the villains are quite straightforward in who they are. If you are a fan of twist villains, you'll be disappointed, but if you enjoy a good villain, you'll enjoy two out of the three villains shown. The weakest member - Grubber - at the very least only suffers from not being funny enough as the comedic sidekick to the serious Tempest.
As for the comedy, the movie goes for a more hi jinks, silly comedy with a few deadpan jokes here and there. Don't expect to a lot of sarcastic remarks or much in the way of deprecation towards their series or its ideals.
Finally, the soundtrack is quite good. There are six sung songs in the movie and they all keep a different beat and genre. Their distinct style keep them memorable, and not only help progress the plot but explain certain characters in an easily digestible fashion.
Overall, it's more of a classical styled Disney movie, and wholly enjoyable to anyone looking for a solidly written film.
