That's the question I ask seen this film.

The leads acting are great. That was all the positive stuff.

Everything else is negative.

The core of the script, this road-movie thing is not that bad to be honest. Could have worked IF this was something like Shot Em Up, or even one of those stupid christian movies like Children of Men. But as an X-men movie it fails on every level. The timeline is completely ruined. I can make the mental gymnastics even to insert the Deadpool movies on the timeline, but this happening in 2029, and 50 years since no mutant been born - incompatible. Maybe if it'd been 2079, I could come up with a good theory (and I actualy did). Then there are the Reavers. I mean those generic, throwaway, cybernetic minions. These are NOT Mojoworld's creations, not even anything special, not even technological marvel monstorsities, just tin soldiers. Or how about an explanation why the Mutant Weapon Program got canceled? Because there is none. Or what about that ending? Where did those kids playing Hunger Games came from? Also have no idea about The Westchester Incident.

The worst sin though is maybe this whole anti-science element how the mutants died out: the Government put fluorid in the water-system to poison EVERYONE. Not just in the USA, but on the whole Earth even! What's next, Flat Earth?
