The first 15 minutes of Indiana Jones and the Last Crusade are set 30 years before the rest of the movie, and teenage Indy has a single day where he is introduced to grave-robbing/"muscular archaeology" as a concept, uses a bullwhip for the first time, gets the small scar that Harrison Ford has on his chin, is traumatized by snakes, and receives his fedora. Solo nominally spreads things out more, but in the course of one movie he gets his name, the blaster, the dice, meets Chewie, meets Lando, wins the Falcon, does the Kessel Run, etc., etc. It's cute until it's not.

For "nighttime mud blasting," I was referring to the scenes when Han is in the Imperial Army on that planet where they're fighting WWI style battles, all of which are in the dead of night and everything is covered in mud, and you can't really see any sense of scale, I think mostly to save time and money during the Ron Howard re-work. It's pretty generic stuff, but it does show war as a not entirely heroic activity (a patriotic, gung-ho officer is immediately blown up, and Han implies they're the invaders), and therefore a certain segment of fans are obsessed with it as a more "sophisticated" take on Star Wars.
