Beowulf is an poem written in the Old English at cca. 1000 C.E. based on a story that was 100 to 300 years old at that time. And yet we have blacks and indians because, of course, Europe was full of them at that time. And also we have empowered women that are fighting with two swords in the same time, because Europe was full of them too. And, of course, we have empowered women of colour because we aren't politically correct enough until we aren't intersectionalists too.
The level of accuracy is low, this version of Beowulf being a wanna-be Game Of Thrones fantasy but is only full of cringe. (I mean, G.O.T. is overrated anyway, but at least it was a decent product...)
So: they have destroyed a beautiful story and turned it into a garbage flooded with historical inaccuracies, some failed unoriginal fantasy and with the so-called multiculturalism. (It is easier to throw in some random coloured people with the purpose of doing some virtue signalling instead of showing the cultural differences between those medieval tribes, innit?)
1/10 is too generous for this. The best thing about it is that it was cancelled.
