I watched it, and I enjoyed it. My only real disappointment is that it doesn't end with "Do The Mario" playing during the credits...

And yeah, speaking as somebody who has thought about writing movies based on video games (and is writing a fanseries based on something that started out as a video game) from a more storyline driven angle... I like that they just focused on the fun side of the games, like it's a movie based on a fun video game series, that doesn't take itself too seriously, which is all it needs to be, if that's what they writers wanted it to be.
