Despite the barrage of criticism, the Marvel Studios film Captain America: Brave New World managed to show a good start. At the moment, the film's total box office has reached $289 million, but to break even, it needs to collect about $425 million by the end of the rental. It is not yet known for sure whether the film will succeed or not, so in the wake of the discussion, we suggest recalling the Marvel film that became the record holder for failures.
Thus, the anti-record for a fall among MCU films belongs to the film Captain Marvel 2. The box office receipts for the second weekend fell by 78% compared to the first weekend. As a result, with a budget of $220 million, the box office receipts worldwide amounted to only $206 million. The film's ratings are also average 5.5 on IMDb.

And if we talk about comic book movies in general, the worst second weekend was for the film Joker: Madness for Two from the DC Universe. In it's second weekend, the film lost 81% of it's box office revenue. Thus, it earned only $207 million with a budget of $190 million.
As for the new Captain America, some critics still believe that the film will reach $425 million, given the lack of serious competitors in the near future.
