Hey, if they learnt from every other failed attempt, including marvels own attempts to combine the mcu with tv shows, go for it.
Which is make a decent standalone film that you need zero prior knowledge to enjoy, and then in an entirely throw away post credits scene suggest there might be more to come.
Then make another decent film, same rules apply.
Then another. Then another.
Then 5 years down the line you have a selection of decent franchises all working fine independently, then bring them together.
Don't churn out some mediocre crap and expect people to buy into it just because there might be a pay off 5 years down the line.
