This is how I'd describe it.
Snyder took a dump and called it Justice League, before he had time to polish it. Wehdon came along and took another dump on it. The result was Justice League 2017.
Now Snyder took a dump and had time to polish it. So yes, you can polish a turd, but its still turd.
I can't say that I will watch it again.
I enjoyed BVS a lot more.
