Ragnarok Is The Highest Ranked Comic Book Movie Ever!

The Tomatometer doesn't measure a film's "rating."  It measures how many critics would recommend the movie or not (regardless of how "good" or "bad" it is).  So the fact that so many critics are recommending it suggests that the film is perhaps one of the least offensive superhero movies ever.  That's another way of saying that you aren't going to find a lot of people who will complain about the film enough to not recommend it.
