I don't think there will be any musical, but if I'm wrong, I'm sure Noah will know how to give it the right context.
I personally don't look at it that way, if Prometheus had a good story, I'd be all for that kind of approach. In spite of what we got I still am in fact. As for first exposure. If viewed in theatrical release order like people ought to we have nothing to worry about.
We haven't had a good execution of new ideas in Alien so far. Prometheus
went from prequel, to almost prequel and then to an expensive 2 hours prologue for an spin-of series...before returning to Alien in Covenant
. But I think that even for a spin-off, it could have been better with a superior script.
If the franchise name gets your interesting thing made f**k it I don't care.
What's the point making new entry in existing franchise, that deviates significantly or even outright contradicts what was presented earlier. Isn't it better to make something brand new?
Because studios are bloody cowards and hate taking risks. So you might as well hijack existing franchises to tell new stories
One of the things that I respect about James Cameron is that he doesn't use existing franchises to exploit the themes he is passionate about today.
