True but that's what the marketing for this has been since start of the year. Looks like WB learnt nothing from the MoS/BvS-SS 2016 era that it can backfire easily too.
"Those people" are not even the target audience. The first movie despite all the hate in the world made over a billion. I know, I know this one won't make that much. But the standard MCU sequel drop lately would have it around $600M-$700M, which is nothing to scoff at in the current CBM scenario.
This will easily have great legs throughout July and August. Re-watched KoTCS last weekend and it wasn't even that bad! Although, I feel some elements from that movie will also be here.
I mean Shazam 2 bombed out of the gate, Ant-Man 3 failed to match the first movie's gross. If a well received GoTG Vol.3 under performs that's a bad sign for both studios. Superman Legacy would be lucky to match MoS numbers and that was coming right after peak DC era of TDK, while Avengers/Iron Man 3 were breaking box office records in that year span.
