To be fair, the majority of they public response was favorable. It has a 62% audience score on RT, got a B audience rating from cinema score, and made crap tons of money at the box office. People liked it.
A movie with Batman and Superman should easily make a billion. I am not all about box office = quality, but BvS should've been a slam dunk. But also Disney caters and honestly pays off reviewers, so no one should think that is a fair opinion to judge from. The general public clearly likes some humor with the superhero genre, although you don't need to overwhelm them with it. Snyder is really the graphic novel territory, although very appealing to me, is not a big box office achiever. Plus, a 62% is still a failing grade lol.
