Matt Singer’s review published on Letterboxd:
My kids loved it — although they did raise some objections to Marty being so singularly focused on getting rich when he had absolutely zero interest in that in the first movie. And they’re not wrong! (Ironically, they had no issues with the whole “Suddenly, Marty being called a chicken is his Kryptonite” that everyone always kvetches about.)
The cleverness of the second and third acts really hooked them, though, from the alternate 1985 to the tiptoeing through the events of the first Back to the Future, and Doc suddenly getting struck by lightning and sent back to 1885, followed by the Western Union telegram and then Marty going to 1955 Doc to plead for more assistance right after he sends BTTF 1 Marty back to the future. Laughing out loud, gasps, desperate pleas to watch Part III immediately, the whole thing worked like a well-oiled pizza hydrator.
