Would a reverse Back to the Future be better?

The idea of remaking BTTF (1985) is so dumb. Would it be an exact remake? Would they update the decades? Will they use the same theme songs and score or make new ones? It's dumb to even try when they won't be making the same exact movie that people have loved for over 30 years. People love those actors, the music and the car. The new one would be new people and I don't even know what the time machine would be. It was a product of its time. There have been tons of other great time travel classics that have came since so why not just be clever and make a new beloved classic time travel film. It's easy; Bill Teds, Bill Teds 2, Idiocracy, Sliders, Hot Tub Time Machine, Donnie Darko etc.

How about Marty is from the 50's or 80's and comes to 2025 instead? I guess it wouldn't work hence the title. Nevermind.
