I honestly don't understand your critiques of how it looked. I thought it looked fine for it's budget. The only bits that looked a little wonky were the nighttime shots of the exterior of the plane flying and crashing. It looked like a budgetary constraint thing and directorial choice thing to make it look more stylized than realistic. But even then those shots were short and they were fine for the budget.

And going forward I feel like a better comparison for Butler movies are the Liam Neeson movies he did for a decade. They're dad movies, usually low budget with the appropriate action and cgi to reflect that, are surprisingly sincere, fun in a good guy saving the day way as opposed to shlocky or 'cool' way, and are just an easy watch with broad appeal. He's not making John Wick movies nor do I think he wants to. He's right in his preferred pocket of the 90's B-tier action movie. And personally I love that he's making these movies that kind of died in the 90's.
