Dan Hudson’s review published on Letterboxd:
This movie could have just been a puff piece. Essentially just Michael J. Fox narrating his own life, it also could have been by the numbers. We see a little of Michael's life now --- interacting with his family, going through physical therapy --- but the majority of the film is footage from his career matching Michael's recollections. There are a couple shots where a body double stands in to get a shot for what Michael is narrating, always shot from the back so we never see a face, but almost all of it is from his TV and movie work, and sometimes lines are edited in out of context from its original meaning, but making perfect sense within Michael's 2023 VO. Some of the footage is quite astounding that it exists, including extensive behind-the-scenes documentation of filming the pilot for FAMILY TIES. And the footage of Michael and Tracy falling in love --- incredible.
There's a reason that Davis Guggenheim has an Oscar --- he knows how to approach his subjects and present back to us the audience more of what we what appreciate about them in the first place. Michael J. Fox is shown to be so effortlessly funny and quick, and the title of the film plays well to show the contrast to one of the biggest stars of the 80s and where they are now. Yes, it is sentimental, but who cares when it is played so beautifully. A documentary about the life of Michael J. Fox could be dour, played as tragedy, but this film is anything but. Both he and this film are so full of life.
