Not to mention alongside Nu Metal come Powerviolence (fight me), funk metal, industrial metal (including NDH like Rammstein), crust metal, sludge metal, crossover thrash, post-metal and alternative metal. Grunge has also helped metal, bringing rise to grunge metal bands like AIC, Soundgarden, The Melvins and Tad. You also forgot groove metal (Pantera, fuсkers!). In 2000s there is a revival of both glam and thrash.
In 2010s not only we got djent, metalcore and deathcore, but kawaii metal as well. And in 2022, deathgaze.
