I suppose that Amazon is looking to appeal to as many new customers as possible. With the likes of this show and (especially) the Lord of the Rings spin-off and the already existing franchises such as Picard, they likely will do.
They definitely have the budgets to create the best sets and attract the biggest name actors, and if they can recreate Middle-earth, Blade Runners futuristic world should be a doddle.
If it will be any good is anyone's guess, but with the money behind it and the world it is set in already imagined, there's no reason why it shouldn't be.
