Being a Batman brand name didn't make it instant success. Batman and Robin is proof of that.
It made more than double its budget back worldwide. Keep in mind it had the biggest budget of all the Batman films up until that time. Just go look at boxofficemojo and see for yourself.
As for the critical reaction, that's just what I heard. You're right in that a movie doesn't have to win over the critics to be successful. That's a whole debate in itself, right there. I think critics can have some influence, though.
