I saw this in the theater and OMG! I found the film amazing! It had quotes from the games, tons of references to Nintendo games in and out of Mario, and the art style is not all the way there for Mario but close enough. I'm also happy with this being faithful to the games, but doing enough of its own thing to stand out. Jack Black as Bowser was amazing! I think Nintendo should hire him as a full-time speaking voice actor for Bowser! It also has a mid and after-credits scene.

Some of my complaints are not knowing Bowser's origin story, this movie using Aha's Take On Me in Kong's place (As much as I like the song, it's pretty much everywhere in movies nowadays to the point that it's kinda annoying.), the flip-flopping character development between DK and Mario (One minute they're against each other and the other they get together.), we only see Yoshis briefly, and Charles Martinet cameos here but not as Mario.

The movie currently has a 7.5 on IMDb and I think its success and fanfare are well deserved. Shigeru Miyamoto produced this film with Illumination and I think this movie was in good hands. Plus, the window is open for future films. They're considering a Donkey Kong spin-off and a Luigi's Mansion film.

What I want for a future installment is an adaptation of Yoshi's Island and/or maybe a Super Smash Bros. film. (I imagine Super Smash Bros. as a video game Avengers.)

I believe that Mario fans can now rest easy knowing that there exists an ACCURATE film adaptation of their favorite game that they can call their own.
