Least favorite is the BBC/Netflix Watership Down adaptation. Whoever decided that what the book about rabbits needed is a goddamn *romance subplot* needs to be slapped. The animated adaptation wasn't perfect but at least largely got the spirit right and didn't do shit like taking away major moments from other characters because we need ~romance~, I'm just really salty that they took the moment when Fiver finds Hazel after the farm raid, which the animated movie used for the famous Bright Eyes sequence, and gave it to Clover instead because again, useless added romance subplot. The miniseries also just doesn't get Hazel's arc during the trek to Watership at all, instead of being an unexpectedly strong leader who makes decisions he just constantly dithers and whimpers and doubts himself to the point it makes absolutely no sense that the miniseries version of these rabbits would name him Chief Rabbit, he didn't do anything! Or how they made Strawberry a girl but kept in the part where Strawberry did a lot to help dig the new warren so instead of the rabbits learning to do things outside their nature to survive -- normally male rabbits don't dig, and the initial group has no females -- it just becomes the girl bunny does girl bunny things (I once described it as 'imagine a book where a bunch of guys who always had their mom around to make them sandwiches go off on their own and have to learn to make their own sandwiches, and then the adaptation makes one a girl and treats it as a girlboss moment when she goes into the kitchen and makes sandwiches for all the boys'). Or how I finally get an adaptation that includes my favorite rabbit, Bluebell, and makes him into a complete idiot bumbling side character.
