I just got to watch it as well. Didn't really like it. They had a chance to make Bowser interesting, but they were too scared to actually commit to the idea in the end, which makes the whole thing very ackward. Also, they butchered Rosalina and gave her the most boring and bland storytelling ever. This is very disappointing knowing how she is pretty much the only character in the Super Mario games with an actually interesting and somewhat deep story.
Everything else is just plain, insipid and with no substance whatsoever with a nice coat of visual effects and soundtrack. Then again... If I wanted gorgeous visuals and a stellar soundtrack I would just boot up the games. Funnily enough, I would also get a better story and some cool gameplay while I'm at it.
