why 5.9

Looks like someone got up on the wrong side of the bed. I don't usually respond to such aggressive questions but I will give you an answer anyway. Whether I like the movie or not isn't the issue and I don't care if everyone agrees with me. I simply pointed out what I believed to be an error in computing the score.

To add on to this point, a lot of older movies are garnering higher ratings from newer audiences because it's being measured against a weighted algorithm that now includes movies from today that didn't exist back in 2000.

For instance, for a 2000 film and measured against other movies of that era (and before it), it absolutely is a 5.9 film. However, we grade art on a gradient based on perspective, and the perspective for this film has changed drastically over the last 20 years, so much so that we can clearly see that -- as per users in this thread -- this film is now best considered a 6.5 out of 10.

Why the whole 0.6 point increase? Because, as you said, today's movies are weighed by critics on an SJW scale, and actual normal moviegoers are weighing movies AGAINST that scale. So if you watch The 6th Day today and compare it to the rest of the action sci-fi schlock Hollywood has produced, it absolutely does come across as a 6.5 film rather than a 5.9 film. It's not rife with SJW-laden dialogue and tropes, and it actually stars a masculine, straight-white male who isn't undermined by POCkers.

So in that regards yeah, you're right, Google users are seeing these films and realizing they're worth more than the salt that the SJW critics have lobbed at such films, and compared to today's boring, nonsensical, politically correct dross, films like The 6th Day practically look like a masterpiece.
