Don't understand why this film get high score

Rating: 6/10 (15 May 2017)

This movie has great cast, and sound like so promising, but in fact the film is not as good what you think. I even don't know why they made this film.
First, the story begin with Cole who did time travel. Then, the story try to convinced us that time travel doesn't exist. It's just Cole imagination, he is crazy guy same with Jeffrey. But suddenly the story change when Dr. Rilley found fact that Cole really do time travel. She even help Cole finishing his mission. So the story begin with their struggle.
This movies seems giving us a lot of puzzle... how can Jeffry release from hospital and suddenly become 12 monkeys leader? We know he is crazy guy. Again, the story try convinced us with Jeffry want spread the virus so Cole and Rilley try to stop them... but the fact he is not... what he's doing? His insane just for animal freedom... and who is the real enemy?? The Dr. Goines' assistant.. what the hell... that guy just show in short time suddenly become the real enemy WITHOUT EXPLANATION!
And the worse thing ever in Aiport scene. After almost 2 hours this film run and guess what... their struggle FAILED WITHOUT SOLUTION! Come on 5 million people going to die when the virus spread but what we got... Just Cole die in policeman's hand when he try to stop Dr. Goines' assistant runaway... after that what the police doing? nothing, what Rilley doing? nothing... the policemen even don't suspicious or try to find out about the happened... and this movie ending without problem solving. We even don't get news about Jeffrey and the gang or even Dr. Goines himself.
I can say this film may be the best performance by Bruce Willis in his whole career but his acting can't save this story. Very surprising watch Brad Pitt act like that, he give great performance but a little bit overacting sometimes. I love the girl who play Dr. Rilley, so beautiful. But I have big complaint why they put Christopher Plummer here ? He did good job as supporting actor but his character as Dr. Groines is useless and not worthy. His character doing nothing during this film run.
So I give 8/10 for the acting and 4/10 for the story
