That is great for what it is, a mid-level marvel movie. This will be hugely successful for that. I don't think Marvel is shooting for $500 million+ domestic for each movie. I think now, if each can get between $800 million and $1 billion worldwide, they will be happy with that.
Avengers: Endgame was the victory lap for 10 years of movies. The expectations for the box office for individual movies out of that success should rise a little, maybe, but not by much, imo. So if a movie doesn't do that kind of business moving forward, its not a flop. FFH should make ~$150 million for the 6 day holiday weekend, which is pretty good. And itll have legs (pun intended).
