One of those movies were I can see what they were going for and the execution of it is hit or miss. How much you sacrifice for your craft and the dread of asking yourself if all of it was actually worth it is always a good premise in my book.
I'm not sure how to feel about the whole "being a movie star can be so tough" angle because at points it seemed they were being satirical about it and at others it felt like they were actually seriously about it.
I really liked the ending though, thought it elevated the whole introspective journey, even if it felt clunky in various parts.
