Looking over the conversation, it seems there is mostly agreement. Both sides agree that DCEU films, BvS in particular, were critical and financial disappointments. The critical disappointment claim hasn't been debated, but the financial side has been. Specifically, some are okay with describing BvS as a financial success, but also call it a disappointment, and there could be the notion that it wasn't even a success; but that is tricky to support since being a financial success isn't the same as saying it wasn't a financial disappointment. There also seems to be some gray area when it comes to the adjectives used to describe the amount of money made or the gap between the high hopes for profit and the actual result with one person saying that the film made "considerably less" than expected, while another said it did make a "ton" of money both in theaters and in home media sales.
In short, one can perceive the nearly $900 million that BvS made toward its $1 billion goal as a successful, yet disappointing, financial result, or one can perceive it as a considerable shortcoming that makes the film financially unsuccessful AND financially disappointing. I personally feel that it was a financial success (and a disappointment), and I believe the studio feels the same way. I think they were content (not ecstatic or satisfied) with the financial result, but naturally they want to do better so they can make even more money and win over more critics and audience members.
