It's an interesting movie... until it gets "un-intelligent" in the end

Rating: 2/10 (14 May 2017)

*Spoilers all over*
The movie is fine. It's pretty interesting all over, but the fact that the ending is so badly written just makes me have to give it 2 stars.
It made me real mad that the writer decided to end the movie the easy way: by making everyone suddenly non-intelligent beings.
Everyone is suddenly non-intelligent and non-normal in the airport, even the security guy who asks to open a biological sample in the middle of the airport (that seems real normal, mister writer). Jose who I'm guessing went to have some coffee after giving Bruce Willis the gun because he seems to be OK with the bad guy running away. The woman who decided to stop trying to stop the wacko, and the rest of the people at the airport who don't seem to find strange that the guy running from Bruce Willis should be interrogated in any way. Somebody with biological material running from a guy with a gun who has just been shot: let's not raise any alarms, let's let him fly all around the world without questioning him first. That seems very normal and intelligent, yes sir. *Sigh*
I'm extremely mad with the ending. What at first was a fine movie... just got ruined due to a really really stupid ending. It's insulting.
What I really don't get is that barely nobody's complaining about the ending. Maybe the 2 stars I've given this movie is lower than it deserves, but I just see so many people reviewing this with nines and tens, that it baffles me.
Characters are all believable and intelligent all the time... But suddenly really stupid at the end. To the point that I got really frustrated and angry.
I'm repeating myself now a lot, but I think that nobody that is at least half-intelligent and has seen the ending can't have felt their intelligence insulted with it's finale. It could have been resolved much better while staying with the tragic ending.
Sorry for the rant, but I just felt that I had to warn intelligent people that the ending might insult your intelligence.
Really wanted to like this movie. What a shame.
