My thing is, while the Russo Bros were successful with their entries in the previous saga…how do we exactly know they’re able to replicate similar success with the Multiverse? Sure as hell ain’t a guarantee like a lot of people portray it to be.
We don't exactly know anything BESIDES the fact that the Russo's are responsible for 3, maybe 4 of the top 5 best MCU flicks.
You can say well look at what they've done since for both Marvel and the Russo's but all you'd be doing is pointing out that there may have been a perfect marriage. They're obviously creative but they don't CARE about these other characters nearly as much as they do Marvel/comic book characters. Based on that, I trust them with the source material more than I do taking chances at crunch time, which is now where you kinda HAVE to nail the big projects that could either carry this forward or tank all together.
The feeling everyone wants restored is what THEY brought to the table.
