Movies' whose critical reception you believe will worsen over time?

There's been discussion around movies like Revenge of the Sith and Spiderman 3 whose critical reception has increased over the past 20 years. But what about the opposite? What movies that are loved now do you think will be looked upon less favorably in the coming decades?

For me I think Deadpool and Wolverine is going to be the good example of this as the score has already decreased a bit from launch. Its so heavy on reference material and cameos that it loses its own identity. This may be fine for many on a first viewing but I believe that as time goes on and people start rewatching it they'll start to look at it with more of a critical eye.

A couple more that came to mind were American Sniper and Zero Dark Thirty. Looking at the reviews from the time they were generally pretty well liked but that has changed since their initial release.
