I have never read the original Manga but seeing the reviews...you know the anime is just perfect. You don't get awesome plots like this these days.
The way it makes you feel anger and sorrow at the same time and shows that everyone has struggled. It will make you cry and laugh at the same time. The bond between a brother and a sister(I watch it with my sister). Tanjiro, Inosuke and Zenitsu the trio's friendship, the jokes and laughter, the storyline and the music..its all so amazing. The scenery is just fabulous one of the best. Can't wait for more.
I can only say that with hardwork, skill and struggle, no barriers are hard to break and no sadness can stop anyone, You have to survive and keep moving and that how legends are made.
PS: The outcome are the cutest.
