The first part of the movie with Sivana, is brilliant. From the car until he enters the cave with the wizard and the Deadly Sins starts talking, GREAT sound effects. I was like wow if this is what were in for this is going to be something special. It didnt quite live up to that for the rest but it was good. Definitely enjoyable.
The budget limitations does show itself in the 3rd act in my opinion, Levi vs Mark Strong fight is fine. Although i wish they went a little further. It felt like they held back a little too much, a little reserved BRING OUT THE POWER AND UNLEASH like your life depends on it.
Also think the rest of the family fighting the sins was a little "low budget feel" in the way they moved and fought although we didnt see too much of it. They had the same color pallet as Doomsday but didnt have the budget behind them as Doomsday did and it showed.
