>>38454209Yeah, that's how the tomato score works. It gives you a percentage of how many critics said it was "okay" or better. 5+/10 is a "fresh", under that is "rotten".
The percent rating is to tell prospective audiences if the movie is generally thought to be enjoyable or not. This is why it's possible to have a 6/10 film with a 90%, which tells you there's a 90% chance you'll think it's at least 6/10. Conversely, a low percent rating and a higher raw score means the film is very divisive, with more critics rating it under 5/10 but enough critics rating it in the 9-10/10 range. A film with a 30% and a 7/10 means that there's a small chance that you'll like it if it hits your niche, but it's not for everybody.
Endgame was a solid 6 or 7/10, and pretty much every reviewer saw it as an enjoyable if mediocre film, which is why the consensus is around 90%. If everybody agrees "oh, okay yeah I thought it was cool", it doesn't matter if it's only alright, it still gets a high consensus rating.
Ultimately it comes down to your own reading comprehension as a consumer and whether or not you trust consensus opinions (tomato percentage) or individual reviewers (metacritic average).
