What...wh...why....why would you make it a musical, it kills the tone of the movie, I get it that he's sick and he imagine stuff and live scenarios, but a musical really...
This looks like a case of a director who's wanted to created something very unique and it got to his head, it's unique that's for sure, but it really doesn't work, at least for me.
I would've much rather a silence maybe just instruments like the first movie in those tense moments, instead of slapping me with some bullshit useless musical that takes me out of the mood. Give me tense silence 100% of the times.
Musical really didn't work for me
