It’s extremely well written, has stunning character development, a series-long story arc that’s amazing, there’s real danger and main characters die, witty humor, beautiful music score, great animation, every person you meet is important later even if they’re just in the back, keeps the distinct elements of the original show strong while still staying modern and different, an amazing end and the twist of being a prequel to the original. And it’s only two seasons long so it’s a fast watch. “It’s all happened before.”
