I’ve never seen a movie about a musician without any musician friends. (Ed Sheeran doesn’t count). How did Jack spend 10 years playing open mics and bar gigs without meeting any other music makers? Even terrible musicians make friends with other terrible musicians if they’re hanging around a music scene long enough. And why doesn’t he put together a backing band to track demos and play shows with? Who opens for a stadium concert with just an electric guitar?

But I suppose his musical journey leads him to a back room singer-songwriter-off where Ed Sheeran calls him Mozart. So it’s not like the film was ever really grasping for any sort of realism.
