There's only been five Comic Book movies in history to cross 1 Billion and people act like it happens all the time. Marvel only has 3 and DC already had 2 with the last films of the Dark Knight Trilogy. Also why do people love to bring up "Deadpool" like it didn't Body the MCU as well? There's only 3 MCU films that have grossed more than "Deadpool", so it outperformed 9 of their films domestic and globally.
Yes Marvel is still getting a cut but it's not in the MCU. Comic Movies crossing a Billion at the global box office doesn't happen that much and it takes the right characterisics for it to happen. "Iron Man 3" did it because it was coming off 2 "Iron Man" movies and "The Avengers". Of course both "Avengers" did it but "Avengers 2" dipped in Box Office but still cross a Billi.
The last two Batman's did it because "TDK" was in instant Classic and "Rises" was highly anticipated. Now this film had everything going for it as far as brand reconigtion. It was still a rebooted Batman and a Superman people are still getting to know (Reeves still have the crown to most) the March release date to me limited it's box office because Kids are still in school. It looks like it's going to tap out just short of 1 Billion but it will gross over 900 Million making it #6 globally behind Avengers 1 +2, IM3, TDK and TDKR.
So there could be an argument that quailty might of hurt it but this wasn't a lock for 1.3-1.5 Billion with the March release . Every comic book Billion Dollar Grosser opened in May and June. I think the ceiling was 1.1-1.2. Now Civil War (Avengers 2.5) has a lot going for it but techinically the "Captain America" films only do decent. "Winter Solider" did improve worldiwide big time. They are hoping Iron Man and Spidey give this film a nice bump and it probably will. But I don't think it's a lock to beat "Avengers 2" with that said it has a Summer release unlike BatsVSupes and way more characters so we will see what happens. I thnk the goal for C.W. is obviously over a Billion.
its alot easier to get to 1 billion now a days. being that DC had the two most recognizable properties in comic book lore the expectations in many places were 1 billion plus easily. to crawl to a billion is an embarrassment and just a sign of the quality of the film, hence the massive opening week followed by the waterfall drop off in numbers to the point where its battling classics films like The Boss
A completely unknown character like deadpool doing more than the two most recognizable super heroes in the comic game is a sign of DCs failure to make a good movie, it actually has nothing to do with marvel, the only people bringing up marvel in that argument are the pro DC / anti-marvel people
and on the point of it being released in march, it was done on purpose by DC. you cant use that as a defense when they did it on purpose, they moved it from May to march to try and have as little competition as possible. it showed in the first week, but the product was so poor that it has no legs to continue to take advantage of the weak competition.
if you have batman and superman under your control and you release them both in the same movie you arent popping bottles of champagne because you are at 850 million right now. you were supposed to be setting the trend with BvS not being another in the group. they know they dropped the ball with this one
