These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Me, Myself & Irene
Covered Up: Most of the soundtrack consists of popular artists of the time performing covers of lesser-known Steely Dan songs.
Hilarious in Hindsight: One of Charlie's sons exclaims "Man, how the hell can they call Pluto a planet - man what kind of planet has an elliptical orbit? This shit don't make sense!" Pluto was demoted in 2006, six years after the movie was released. while we're at it...
Critical Research Failure: Almost all planetary orbits are at least a little elliptical. A true oddball orbit would be a perfect circle.
Shout-Out: The narrator is voiced by Rex Allen, Jr., the son of Rex Allen, who was the narrator of many Disney wildlife films. One of which was Charlie the Lonesome Cougar. The narration was done in a way to mimic these films.
The Woobie: Charlie. The second you see his kids being born you will feel sorry for him, and it only increases as the film goes on and you learn that the entire town is laughing at him behind his back and he knows it, but is too nice to do anything about it.
Jerkass Woobie: Hank. He's the one who has had to deal with all of Charlie's repressed rage for twenty years or so, and never gets out to express it. He also notes to Irene that before Charlie's wife left him, their personality was more integrated; when she left, she left both of them, and that was the point when Charlie split off the Hank personality and locked it away.
