Well, X-Men numbers aren't great but that doesn't really help Warner. That's like when Apple has a year lower as expected and you try to say how great it was because LG did also bad.
Not to forget that all the other X-Men movies weren't big either (well, Days of Future Past got a nice revenue bonus for good reviews and word of mouth). You wouldn't really expect this one to be big especially after we had already some superhero movies this year (I mean, many people don't watch a movie every few weeks in cinema especially all from the same category) and with some other decent sized releases before and after it. BvS released at a very good time without much other stuff in the cinemas.
It's at $265m WW right now and has still to release in China and japan. It has to beat $460m to be the second highest grossing X-Men movie.
And it won't get my money, saw already too much superhero stuff this year.
