If movies mutate into musicals

I was a few years ago skeptical when I stood on a London escalator and was lifted along on a series posters who applied any musical adaptations of successful films.
Then this offer fluttered into my mailbox: MATILDA THE MUSICAL, and the reviews were good, I am Wherefore, my inner voice repugnant to decided to buy the "good piece".
Well, it was an educational decision. I should have but to listen to my inner voice.
"Such a crap!" is still one of the more lenient expressions that come to my mind. But what is one to do? Apparently, the public demands it, to sit only with things apart that they kennnen instead to embark on something new.
Inspiration can not be enforced. That shows me this musical again clearly. Others may be there quietly disagree. Mir but handed it to say really can: NEVER AGAIN BAD GOOD adaptations books and movies!
Thank you very much for this instruction.
