And TDK was huge OS for that time period. Just because we had the OS grosses of Potter, LOTR, and Titanic that already existed back then doesn't for a second mean that was close to the norm. Hitting 300m+ OS was still a big success. Hitting 500m+ was still massive. IM1 wasn't a big OS success by any stretch, but neither were BvS or MoS. And what's their excuse "in context." They had a far wider expanded market to work with and the two most well known comic book characters ever across the globe. Iron Man was literally a non-entity outside of DOM audiences as a character when the film hit. So let's really talk context here and try to tell me how they were more successful?
As for that last statement, so then are you telling me it's harder for the big event blockbusters to get to 300m+ DOM these days than last decade?
