If you are in the camp of liking Ken Russell, you are going to love this movie. If you like Mahler's compositions and think you're going to get a straightforward biopic (more on this later), you're in the wrong place.
This film is beautifully shot, the acting is over the top in many cases, the imagery will at times be disturbing, the metaphors will run deep, like all Russell's movies.
I just heard of Georgina Hale's passing in January of this year (2024) so was drawn to watch this film again because she was fantastic. I know she won a BAFTA for it, but she should have been given more recognition outside of the UK for this role.
I want to return to the term "straightforward biopic" now. By that I mean the cookie cutter, sanitized tripe that moviegoers normally eat up like Bohemian Rhapsody, Rocket Man, A Beautiful Mind, etc., that take real people who had very interesting lives and then manipulate, fabricate, and distort to give us our feels but no substance. You're better off just watching a documentary in most cases.
If you're going to do a biopic, I say go all in like Ken Russell does. While you may get his version of the story, at least you're going to be in for a beautiful and wild ride that will also make you think.
