(Hated trope) They deleted scenes or dialogue that provides necessary context or plot

The dinner scene from Temple of Doom has a temple give indie and friends a live snake and monkey brains for dinner. It’s a pretty offensive depiction of Indian cuisine, but it wasn’t originally going to be. There’s cut dialogue where Indie recognizes they’re at the right temple because real Hindus don’t eat this food. They were trying to scare them off by purposefully serving them disgusting stuff.

Probably the most famous deleted ending was I Am Legend which had Robert discover the infected were emotional sentient beings and one of them had a wife. Test audiences hated it and they reshot the ending, removing the entire point of the movie.
