Rather than going through the events of the life of the sculptor, Rodin is only showing glimpses of it like Quotes, moments of works or moments of love. The problem with it is, though the chronological order is preserved, that the spectator is completely lost with untold names or missing events and you always need to think about what happened before in the movie to finally understand what took place an hour ago, which is completely annihilating the empathy for the characters because you can't feel the same as them because you have no idea what just happened.
In addition to that, the scenario have no real purpose, the movie is starting nowhere, and is ending nowhere. Moreover, there are totally useless nude scenes, which is sometimes embarrassing because its going nowhere and is never justified. I'm OK with that, but there must be at least 20 minutes of these, and because the movie is often boring and overall too long, it's annoying.
