I’ve been meaning to write about what makes the humour of the G5 movie tick.
If you know about G4, then the whole premise of G5 seems kind of silly and absurd going in. But the movie takes the idea that the audience knows better than the characters and doubles down on it. Rather than being irreverent and self-aware, the movie is unapologetically silly, and takes itself completely seriously.
Meanwhile, dry humour is a part of how intelligent people communicate. (Sometimes I even pick up on it.) The use of dry humour is how the movie telegraphs which characters are the smart ones (Sunny, Argyle, Hitch, Izzy, and Zipp).
The end result is a highly amusing contrast of dumb and smart. And a lot of the secondary and background characters end up feeling like real horses: kind and gentle creatures that can get spooked, and often need a “voice of reason” to guide them.
