1.) Suicide Squad is not a sequel to Batman V Superman. It's like calling Winter Soldier a sequel to Thor the Dark World.
Course doing 750 in it's opening week is very impressive, but multipliers aren't done of opening week. (I'm being pedantic.)
Also, nice job not including all the Superman films in your chart, just to boost your point. Superman and Superman II made more than BvS adjusted. BVS sits at 8 out of 14 adjusted. But behold, it beat Quest for Peace and Superman III, that's something.
End of the day, it's how the OP wishes to declare it a loser, and you can argue that he's wrong all you want, but his definition is BVS didn't make as much as it should have based on clear interest in the film, which is shown by buzz and opening weekend, and how interest clearly dropped off after release by the one of the worst multipliers ever seen by a big budget movie. And comparing it to Twilight is pretty bad, when movies that only appeal to teen girls and Baumer has more GA interest after it's OW than BvS...well...
You can call it a Winner, but then again, that's your opinion. Mine is that it BvS did poorly relative to what it's potential was, and left a lot of sour tastes in a lot of people's mouths. It hurt the franchise more than it helped, and that's more a loser than it is a winner.
