I would like to call this a fan movie.
The inner core of SpongeBob has been lost from beginning to end. SpongeBob is definitely not such a vulgar preaching story. Its anti-routine and deconstructive nonsensical humor are the core of its comedy. Rather than confessing each other in the "we are family" style, it completely violates the role and personality that have been deeply rooted in the past.
Not to mention the main storyline of its big adventure, it is not as interesting and fit the original as the "SpongeBob SquarePants Adventure".
