Look past Mario & Luigi's ethnicity & relationship, and you will find that this movie is GOOD! like really good, I'm not kidding. For a movie releeased in 1993, this film looks fantastic. Koopa's city looks much better than what CGI would do today cuz it really looked like a city built from the ground up. A lot of characters from the game are in it, including "Toad", & Dennis Hopper was very fun to watch. Actually, he was always fun to watch. IDK why this film gets a bad wrap, people say it's the poor man's "Waterworld", but this film came out before it. Give it another watch, cuz it was definitely ahead of it's time. I've seen much worse video game movies in my day.
Super Mario Bros. is the sort of movie that would win every Oscar in Hollywood if it were reinterpreted as an existentialist take on the plight of the modern plumber his need for companionship, and the nature of evolved humanity.
But it's actually pretty crappy. What's even sadder is that when the project was first started, a very promising script was written that would have stayed much closer to the game in the tone of a child's fantasy movie. But when the directors were brought on board, they wanted to go with their own "vision."
Bonus Trivia: Ask Bob Hoskins what his biggest regret of his career is, and he will tell you straight out, "Super Mario Bros."
