K-12 is just as it says-- an enchanting musical with a unique touch and wonderful aesthetic. I think people should see this film for its wonderful aesthetic and visual representation, but dont watch it expecting good writing and a plot.
The musical aspects (songwriting, choreography, and singing) of the film are amazing as usual with Melanie's work, but there are many potential plotpoints in the film itself that are just touched on once and never mentioned again. Some songs made seamless integration into the plot, for example "Wheels on the Bus", but others appeared out of nowhere and brought nothing to the plot, like "Strawberry Shortcake".
The movie's timeline is through the school years of Crybaby, but for most of the movie you couldnt tell at all what grade she was in at that time. Along with this, most of the characters are forgettable and dont have defining personality, but hey, at least it looks pretty!
I do think that Melanie put too much on her shoulders for this film. She wrote the script, directed, was the lead actress, did all of the songs, and edited the whole thing-- I applaud her for all the effort she went to make this film. For all of this being new to her, I think she did well, but I think that she should take it easy next time.
The film left me a little disappointed with more questions than answers, but at least I left the cinema with 14 new bops to add to my playlist.
