The few wide shots are pitifully staged, rendered in shameful CG for our age, barely give a sense of where we are, and, in the case of the funeral procession, are accompanied by awful sounding crowd singing.
I'm not sure the big name actors can really sing or not, I'm not an expert, but what's sure is that it wouldn't have been too difficult to get better results, with lesser known people.
Don't see it, unless you have no way of seeing a professional stage version, and even then...
