That's the floor though. Given Marvel's current winning streak, there's a strong chance of it breaking 300 million DOM and 750M WW. If it's genuinely great, who knows?
My point moreso is now is not the time to downplay Marvel's ability to elevate obscure characters to superstardom.
Don't sleep on Captain Marvel. There is still a real hunger for the first female led MCU movie. I've been saying Strange numbers are the floor and I'm standing by that.
I'm being conservative and guessing a 2.7x multiplier for a 550M DOM finish. That's average legs for a Marvel movie. 600M is very possible though. If next weekend is under a 55% drop then I'll definitely bump up my predictions.
I'm not sure what to make of WW2. How often do sequels to 400M+ DOM movies outgross their predecessor? I think it will open in the 150M range no problem, but its legs are a toss up to me.
