Luckily, this Madame Web thing isn't technically a Disney movie. It's only branded as a Marvel product, but Sony Pictures takes the hefty financial loss for it. And yet the damage to the Marvel brand from this bad product still exists to an extent.
Honestly, Madame Web doing this poorly can't be spun as a good thing for Disney's investment in Marvel, can it?
Unfortunately, yes. The way for Disney to fix this is to start releasing movies that at least break even at the box office.
Or even, and this is where it gets wild, start releasing movies that make a profit at the box office. That is, make a profit before they get sent over to Disney+ so that separate division can lose hundreds of millions of dollars per fiscal year in addition to the losses at the Studios divisions.
