Condensing one of the longer Dragon Quest Games into a 1hr 40 minute movie is no easy feat, especially when you tack on a, "unique" subplot" , and this movie sure falters for it. Story moves too fast to really settle on any side character and lots of the plot feels unnecessary in return. Surprisingly the dialog is decently written and most of the jokes land, the animation is also really beautiful and was able to barely keep my entertainment throughout the movie.
Could have been so much better. The movie means nothing to you unless you played the original game. If you did play the game, this will bring back so many memories - it was so nostalgic, I bought a SNES to play it again! - and for the most part, they get it pretty right, but the game is so vast and expansive, it was never going to fit into one movie. The animation is good and the story is fine but the-all-too-meta last act was a little too much and upended what was otherwise a great experience.
