Is this a joke, when had Wonder Woman an especially big presence in Superman comics, let alone stole him the spotlight or make him look bad?
Even in a League of One, a story where Wonder Woman was literally going all Batman on the Justice League still had to include a pointless and downright disrespectful scene like this:
And that's just the tip of the iceberg of why the announcement that Superman will appear in Wonder Woman: Evolution does not sound like a good thing, the only reason why that might be not as bad as in the past is that DC has seemingly changed to a degree, and there is always the chance to get lucky of course.
