I think the take it too far is debatable. After several viewings, my takeaway from the movie is that getting to the top, becoming legendary can destroy yourself, your personal life. But it seems to leave it up to the viewer as to whether or not thats good or bad or too far. For some, sacrificing their relationships and sense of self in order to become revered as one of the greats, might be worth it. Of course, thats a bit controversial given the explicit abuse in the film, and also imo begs the question; is it not possible to become great without the abuse and destroying yourself? The movie doesnt really address this but surely not every great artist required a mentor throwing chairs at their heads or maliciously manipulating them, right? In any case, a great movie and one that really makes you think.
