I've seen people complaining that the movie is nothing but fanservice, that only the people who played the games will enjoy it, and you know what? they're right, and i like it more because of it, fuck general audiences, most videogames adaptations always shit on the source material and seem to hate the fans with a passion, remember this shit?
Always making stupid changes, either to stir up controversy or to chase the "wider audience", so having a movie that is pretty much a love-letter to the fans feels like a breath of fresh air, especially in this day and age. The Mario movie fully embraces the games, it fully embraces being a videogame adaptation, it is a celebration of both Mario and DK's legacy, to me this movie is just about as perfect as a Mario movie could be.
