The Sacred Blacksmith (anime), had, initially, a few interesting characters and a promising plot but, sadly, it wasn't developed any further or properly.
@codewiz definitely Kimetsu no Yaiba and, so far, Dr. Stone :)
@tchx84 I watched the first 2-3 eps of Dr. Stone... It wasn't bad, but also didn't get me.
@codewiz OH S***, I forgot... VINLAND SAGA!! I am really enjoying it... its brutal!
@tchx84 I followed your advice and watched the first ep. It's not bad at all, and... quite brutal! Just as promised
