Michael’s review published on Letterboxd:
I very much consider myself a fan of Nirvana but have never really delved into the personal lives of any of the members. This documentary puts another meaning behind the music. It's heartbreaking to see Kurt enter a downward spiral that he can't seem to get out of. From feeling rejected at a young age to ending his own life at age 27. Montage of Heck is the Nirvana documentary fans have been waiting for. Never seen before footage and demo recordings make this something special. I'm going to go blast Bleach as loud as I can. Definitely worth a watch if you like a good music documentary.
