I have a few that I gather most people disliked:
Avatar and Titanic by James Cameron.
Showgirls by Paul Verhoeven.
Interstellar by Christopher Nolan.
Star Wars Rogue One by Walt Disney.
X-Men Origins: Wolverine by Gavin Hood.
Most people actually don't hate Titanic its 7.8/10 on imdb, 89% fresh on rotten tomatoes and 75 on metacritic.
