Analysis Awesome Film Fridge Funny Heartwarming Laconic Main Trivia WesternAnimation YMMV
Awesome Music - "Canned Heat" by Jamiroquai (used for THAT DANCE SCENE) and "We're Going To Be Friends" by The White Stripes.
"The Promise" by When In Rome.
"Music For a Found Harmonium" used at the end when everything is being tied up. More like Crowning Music of Heartwarming, but still.
This list can't be complete without "Forever Young" by Alphaville, which is played at the school dance. Or "Time After Time" by Cyndi Lauper for that matter.
Crowning Moment Of Awesome: The state of Idaho passing a resolution honoring the filmmakers for portraying Idaho so positively.
Funny Moments: Oh, so many. The crotch zapping time machine, Napoleon's dance near the end, Kipp's attempt to demonstrate the strength of a Tupperware bowl using Rico's van, the list goes on.
Fountain of Memes: Everything Napoleon says. "Gosh!" "Frickin' idiot!" "I like your sleeves." " Fine!"
Hype Backlash: Some have found the film to simply be boring and awkward (even though that's sort of the point).
Love It or Hate It: Netflix's recommendation system, which is generally quite accurate, just can't predict how people will rate this movie. 
Nerds Are Sexy: Napoleon developed a huge bevy of fangirls. Enough that some newspapers and magazines ran articles about the phenomenon.
So Bad, It's Good: Done intentionally, which is part of the appeal.
Watch It for the Meme: Or at least, the lines all your friends have been repeating ad nauseum.
