Still not a particularly original concept.
It doesn't matter? Execution is more important. The concept of "family members are separated and go through great lengths to reunite" is also not an original concept either but did people dump on Finding Nemo about that? Stories about similar concepts are fine as long as the execution is unique across them. If I said "It's a story about a boy and his dog" would you think I was talking about Lassie or Adventure Time? Turner and Hooch? Psyche I was speaking literally about the movie A Boy And His Dog. Should no more stories about a boy and his dog ever exist since it's not an original concept?
Yeah, it sounds like a visual gag in a Shrek movie.
The Shrek movies have no modern anything in them though. No modern houses, no modern technology, it's all set in Ye Olden Times. They don't even have like olden versions of modern things as sight gags beyond a couple fast food logos in 2.
Isn't this what that Will Smith Netflix movie (Bright?) is doing?
I dunno! Is it? Cool if it is, it's a neat concept that I'd like to see done in many mediums, I'll look into Bright. I can almost promise its execution will be different from the new Pixar movie though if that's what you were angling at.
Edit: Just looked it up and at its base level yes it's "magic in modern day" but the execution is "Two Los Angeles cops hunt magical creatures" which is completely different from "Two brothers learn about the father they never knew". Bright sounds sick as hell though
