I realize that BvS has a lower cinemascore, but being as there is no way to quantify that into dollar amounts I decided to just look at the hard numbers. Especially since GI (A-) and FF7 (A) are both higher. GI has a RT score of 28% that is similar to BvS's 29%, but both way off of FF7's 81%. Looking at the numbers, I still think 2.4 is a good multiplier match for BvS.
Ignoring the numbers, I personally think that BvS will be under Deadpool domestically. I just don't have any evidence or statistics to back that up at the moment. Just based off a gut feeling and the fact I hated MoS. I'm a huge Superman fan, he's my favorite superhero, but I almost walked out of that movie. Never had the urge to do that before or since. Have no plans on seeing BvS or any other DCU movies due to that experience. Which is a shame since the DC TV shows and cartoons have always been awesome. Especially The Flash and the cartoons; Batman: The Animated Series, Superman and Justice League.
