Weird that this has such a low RT score...
As people are pointing out online, the Rotten Tomatoes ratings usually fall in Marvel's favour - a lot of the mediocre reviews of this film still have "fresh" ratings due to the scoring system.
Here are some examples: https://twitter.com/jessehawken/status/1544366139806973953?s=21&t=L5zVkcmDVMztIVMnc16nMg
Rotten Tomatoes also gave Tomatometer accreditation to a ton of comic book sites, fan blogs, etc. a few years ago, which review this genre of movies favourably. For example, Comicbook.com is RT-accredited.
So, as much as fans complain about critics, Tomatometer - by design - usually leans in favour of Marvel films. It's strange, even for a non-fan like myself, to see that 'Thor: Love and Thunder' already has a lower score than 'Minions: The Rise of Gru'.
