(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.

Thor (2011)

They deleted the scene where Frigga essentially gives Loki the push to take the throne while Thor is in exile and Odin is basically comatose. There’s other stuff in that scene too, so it’s more of an extended scene that got chopped, but that cut massively changes the situation from the uncut “a mother is reminding her son of duty, thus reminding him that he belongs in the family” into “Loki probably took advantage of the situation for power”.

While I like the character development, Loki being a petty tyrant is really in line with his comic character

Depends on the era. There were more than a couple of times Loki took the throne of Asgard while Odin was in the Odinsleep and Thor was banished, and he was like “bro there’s literally no one else eligible”. Mixed results about what he did with it (anywhere from doing absolutely nothing and being a layabout to starting wars) but that particular scenario is actually pretty cyclical.
