No Way Home isn't a good comparison.
It'd be like if next month WB released a Batman Movie set in the Multiverse starring Keaton, Bale, Affleck, and Pattinson and then saying "Well why didn't Black Adam do those numbers?".
Black Widow, Shang-Chi, and Eternals were standalone MCU films released during Pandemic Restrictions and made 219, 140, and 162 million respectively on opening weekends and yet were all called "flops" by certain fan bases yet Black Adam has been hailed a success making the same amount or less at opening and with no Pandemic Restrictions.
I think some just want to point out the hypocrisy.
Like Black Widow, Shang-Chi, and Eternals Black Adam did fine.
