Deadpool 2 is a miraculous movie. Thankfully fans ate up the weirdest parts of the first Deadpool movie, so it gave the creators permission to go all out in Deadpool 2. You thought the first movie gave no F**KS? Deadpool 2 makes fun of Marvel, itself, DC, and even Ryan Reynolds own career. It feels like a parody superhero movie that uses actual superheroes.
Deadpool makes a lot of things right in the Marvel universe, especially in the post-credits scenes where Deadpool uses time travel to simultaneously make jabs at superhero movies-past as well as correct some previous flubs/fan-hated moments. The biggest restoration this movie does is finally give Juggernaut his due. This is the Juggernaut we've always wanted to see. Sure, Vinnie Jones in the third X-Men movie was fun, but it wasn't Juggernaut.
