Factors I think that are landing this movie below the hopeful predictions: Man of Steel did okay in the box office but wasn't an event movie or critically liked. So returning to those events isn't a massive draw. Keaton was last Batman 31 years ago. There have been 5 other live action Batman actors since. And this isn't a Batman movie. The audience connection just isn't there. Supergirl is Superman's cousin. That the interesting start point of the character and they are doing this without Superman. Ezra can't do promotion. The cheapest and most effective marketing you can do is to get your man actor some interviews. This didn't and couldn't happen with Ezra. The trailer CGI is bad. The DC brand is not good at the moment. Flashpoint is terrible for a character we hardly know.

They really need to change their name.

Minor maybe. The issue is any re release has marketing and other costs. So it's not an issue of getting more profit it's an issue of making more money than the additional costs. Also theaters won't give a rerelease that many showings and most probably won't show the movie at all which greatly reduces potential income.

Lion stopped that happening this year. That's the way it goes, either you get 1-2 big films or none in a year.
