Best one of the three imo, and I liked the first two. Ryan Reynolds and Hugh Jackman have really good chemistry together. Jokes hit more than they missed, good action too.
Thought it was a nice tribute to all the pre-MCU and Fox superhero films, all that was missing was Ben Affleck's Daredevil (Though they do reference him at least). Cool that the Deadpool Corp appear too finally.
All-in-all: Fun movie, 8/10
Natural as in not on gear (or less gear at least)? Because I still think the dude is juiced to the gills, he just maybe has a bit more body fat.
