Well I didn't want to have Civil War as n°1 because, well, where's the fun in that ?
But I also think Finding Dory is in a really good spot, generation wise. People in their early 20's (hi) grew up with Finding Nemo (it's one of the first films I remember seeing in the theater), it's beloved and Pixar just proved last year they can still do great numbers. Also I don't see much else competing with it in June : it's basically just Independence Day and TMNT I guess ? Also I'm hopeful it will be good.
Neigbhors 2 is my "rauchy comedy" slot, because looking at previous years there's generally one of those.
And after Jurassic World I'm guessing a nostalgic 90's blockbuster has to do well, right ?
