Gerry Conway doesn't own these characters. I loved BvS and thought it was the most sophisticated superhero movie that's been made, yet. BvS was DC's second film and outperformed everything Marvel put out until its 6th movie (Avengers). For supposedly always hitting a homerun, exactly 3 Marvel movies have outpaced BvS...Avengers, Avengers: Age of Ultron and Iron Man 3. Why don't we see how JL does (which is more comparable to Avengers) before we say everything is wrong.
First 5 Marvel movies:
Iron Man - $585 million
The Incredible Hulk - $263 million
Iron Man 2 - $624 million
Thor - $449 million
Captain America - $371 million
First 5 DC movies:
Man of Steel - $668 million
BvS - $864 million
Suicide Squad- ?
Wonder Woman - ?
Justice League - ?
So it is very likely that all 5 of DC's first 5 will outgross Marvel's first 5. Everyone can stop with the DCEU funeral
