Well, I watched the movie. Here's what I thought about it. I'll hide any spoilers in case you want to watch it.
Music
Being, well, a musical, there were a lot of songs, and I think they were good. I think the best one was For A Moment, but Sweet Tooth was also kind of funny. Besides the lyrical songs, the background music was also fitting for the type of movie it was. There was a lot of piano, but despite that, most of the silly and fitting for the type of movie it is. I will say that while he's not a
bad singer, Timothée Chamalet is better at acting than at singing.
Writing
I think that this is also supposed to be a comedy movie. If it is, then Paul King and Simon Farnaby did a good enough job in that department. It never made me laugh out loud, most of it just made me smile, but there were parts when I came close to doing it, like Sweet Tooth, or how one of the chocolate shop owners always explains things that are supposed to be subtle (it makes sense if you watch it), or the comedian character. It also knew when to be sad and not interrupt with a joke, like when
Willy's chocolate shop is destroyed, or at the end of the movie where he finds out that his mom's secret recipe wasn't what you put in it, but who you share it with, or just the character's backstories, especially Noodle's. I think it all comes together in the third act, that's when it all comes together. Finally, I think it's funny how this one piece of chocolate that Willy gives to the guards just simulates them being drunk.
Conclusion
I think the movie was good at being a backstory for Willy Wonka. You should check it out.
I'm only giving it a 7.8/10, because there was too much chocolate I give it an 8/10.
