It felt fresh, and the fourth wall breaking was new to the superhero genre. It wasn't about saving the world, it was about saving his girlfriend and getting revenge. The jokes were hit and miss but they hit more often than not for me (and others, I assume.) And the action was pretty well directed (plus the R-rated gore helped differentiate it.)
Overall, just a nice lean comic book movie, which is what the world wanted after Avengers 2, BvS, Suicide Squad, Civil War, etc.
Logan looks to be in the same mold, just a stripped down story that happens to have comic book characters in it. Fox killing it with their X-verse (Apocalypse was good.)
