The new Mario movie was pretty good. There were a few times that I thought “this doesn’t belong here, and they just wanted to shove a reference in”, but overall, I think they did it justice.
Can’t speak for everyone, but the reason that I care when one of my favorite IPs has a terrible movie, is because the terrible movie ensures that a good one will never be made.
They did a great job with Fallout, and now they are making a second season.
Then there’s Borderlands.
I still haven’t seen it, but I already know that the Borderlands movie I would have loved will never exist.
