My assessment might seem strict, but those who’ve watched it will understand that the movie falls short in many areas. The production quality was acceptable, particularly considering it wasn't made by Disney, Pixar, Dreamworks, or Sony; it’s adequate for what it is. It seems geared toward very young children, and viewed through that lens, it’s a more agreeable experience. The character designs were passable, but the plot felt familiar—a predictable dystopian narrative where a dangerous figure attempts to destroy the planet, a family reunited after years apart rallies allies, and the final confrontation decides the outcome of a large-scale battle. To me, it resembled something made for television rather than the big screen; truthfully, it would have been better as a TV series. It shares similarities with 'Trollhunters', where a young protagonist discovers a powerful tool and undergoes rigorous training to confront an evil power, each installment presenting a new action or adventure. That format could have resulted in a really good show. Although the film didn't particularly resonate with audiences, I wouldn’t call it terrible; it’s watchable enough, but not entertaining—just something to fill time. There are many better options for that purpose. Showing it only to young children might be justifiable, as they aren't able to distinguish between quality and simply enjoy what they see. _3/10_
