I saw the Mario movie. 

The Mario movie is totally fine. Inoffensive (unless some licensed songs offend the sensibilities). Seth Rogen is the worst in the movie because he doesn't even try so Donkey Kong is just "Seth Rogen" and he even does his laugh. It is very thin on plot and very quick on everything to the point where sometimes it's like watching a speedrun of Mario. Zero fart jokes and zero wink at the camera ha-ha reference jokes. But on the topic of references my god the references and easter eggs in the movie is insane. Like someone could go frame by frame and still miss some that's how many there are, from names of shops or pictures on the wall or visual gags or blink and you miss it stuff. Every mainline Mario game gets referenced even if I missed the Sunshine one I'm sure it's in there somewhere. 

If you want a deep plot then look elsewhere but if you have like 90 minutes to kill then it's a fun watch, doubly so if you're a Mario or classic Nintendo fan. And the remixes of Mario music are just...they're real good. 

That said, Illumination would not be someone I hire to do a Zelda movie. They could do Kirby though.
