Also WB really panicked over how bad the reviews were for it. According to Ayer, all the critical reception to BvS is what made WB take control from the Suicide Squad from him and try to make it lighter.
They're probably more likely to consider Superman a success because
1. It has an abnormally large domestic/international split. The 2-2.5x rule that people normally float about is assuming the Dom/INT is 50:50. This is good for Superman, as studios take a lot more of the cut from domestic profits.
2. It has good critical reception so it doesn't taint the brand like BvS.
3. It has strong legs for a comic book movie (at least domestically), meaning audiences actually like it and it has good word of mouth. Nobody wants to make a sequel for a movie that has a 70% dropoff like BvS did, because that means audiences hated it, and probably won't come back for the sequel now that they're not duped by marketing hype.
