What campaign? It's the same youtubers who always call any new MCU film/D+ outing "a failure".With the smear campaign against the film, it's done well
Every popular IP has to deal with that.
And yeah, while I enjoyed the film,it had its problems, but you always have people who shout: "I could do better..." with no r eal clue how a large budget production works.
If you expect perfection or expect a 180 million budget to compare to a $400 million budget (Avengers: Endgame); yeah your gonna be majorly disappointed.
If someone ever comes up with a reproduable formula to make a great blockbuster for cheap that pulls 1 billion at the box office eveyrtime; every studio would jump on it.
And anyone who just quicklyopines "Easy, make a good film..."

Just shows you've never produced anything for wide public consumption because ending up with a end result that almost everyone loves is rare and sometimes the script itself has little to do with it.
