Odd movie indeed. To think Michael Corleone got old and turned into this whack job.
I think they did an admirable job at sluicing between theater and reality (or their versions of either) every time you walked on or off stage, you got to feel the pancake makeup and smoke and mirrors that is Broadway . The audience sees something soooo different than those behind the scenes and if nothing else in this - I think they tried hard to both enunciate and blur the differences of those worlds and how to a once B-list actor/super hero, turned wannabee theater actor, those worlds can sometimes have the thinnest of curtains between them.
I thought the endless maze behind the stage where the drummer so seamlessly lead us from one area to another until he finally shows up in the scene himself was done well, and the scene leading onto the street too.
I too couldn't watch a ton of this style movie, but it was good to see some thinking OUT SIDE of the box of Hollywood films.
