Most Disappointing Sequel?

Back due to the debate about the merits (or lack thereof) of Gremlins 2 in the Gremlins 3 thread

Been over a decade since the last post so there should be a lot more candidates

A lot of my new ones are MCU and Star Wars related

Thor 2 and Love & Thunder, Iron Man 2 & 3, Age of Ultron, Wonder Woman 1984 and Batman vs Superman

Last Jedi and Rise of Skywalker

Coming 2 America
