If you like Mahler's music and have read something about his life, then this film is unlikely to meet your expectations.
I found it to be an awkward collection of badly stitched together, largely badly acted parodies, improbable events and dialogues. The actor playing Mahler does make a brave effort, even though the script would have him looking extremely young and healthy even when dying, and behaving rudely much of the time. But for the rest... Alma Mahler looks wanton and superficial, and physically not at all like Alma Mahler. Mahler's father looks just embarrassing, with many other characters being a collection of freaks. Give this a good coating of 1970s dubious experimental ideas and listen to the shrill recording on the DVD, and you are done.
