Melanie Martinez has always been one for interesting visuals and concepts, and nothing exemplifies that more than K-12. The music video portions of the movie are beautiful. Amazing sets, catchy songs, gorgeous costumes and intricate choreography, but it seems as though aesthetic was the main focus of the movie. The plot - if you choose to call it that - is definitely where the movie falls flat. It's clear that Martinez's heart was fully invested in her directorial debut, but the writing itself reeks of immaturity. The integration of the songs itself is also done very poorly. While some songs like 'Wheels on the Bus' are weaved carefully into the plot, you also have abrupt starts and stops of scenes for songs like 'Teacher's Pet'. As a Melanie Martinez fan, though I can admit its faults, I liked the movie. For the casual viewer? I think you're better off watching the visuals themselves as opposed to the full hour and thirty minute feature film.
