You know, this raises an important point. A few days before the film opened, Kinberg said: "I am proud of it, It’s not a disaster. It’s a good movie."

Now he says: "We didn't make a great movie last time out. I think we learned a lot of lessons from that experience."
So just before release, after he had seen the completed cut of the film, he made
statement 1: 'I am proud of it. . . It's a good movie.' and now he makes
statement 2: 'We didn't make a great movie last time out. I think we learned a lot of lessons from that experience.'
What happened between Statement 1 and Statement 2? The movie didn't change. The only thing that changed is the movie that Simon Kinberg thought was good bombed at the box office.
Why would anyone believe he truly learned anything meaningful between Statement 1 and Statement 2? He's still the same dumb guy who thought that piece of crap he gave us was good. He's just changing his story now because popular opinion is against him.
