I think people are clouded as it was a good piece of cinema, rather than the brilliant amazing film they think they watched.
Various ridiculous elements were in place.
Super powered kids, being chased by armed mercs, mercs decided to try to capture the kids and grab them to bring them back, yet not a tazer in sight.
It takes a death before the kids remember they have superpowers.
Then they finally start to use them.
What is so safe about crossing through a forest into Canada?
Mercs with guns might not be looking at their maps. They might even consider shooting their guns.
There are issues, the overall idea and arc within the plot is a good one.
The concept is good, Patrick Stewart and Hugh Jackman are good, the kid ain't bad, everyone else is a bit meh.
