Ultimately, it’s a character-focused drama that uses the world of competitive table tennis to delve into the characters’ inner lives.
‘Mononoke’ (2007)

As a huge fan of atmospheric horror, I’m completely captivated by ‘Mononoke.’ It follows a mysterious character—the Medicine Seller—who wanders around Japan dealing with incredibly dangerous spirits. But it’s not just about fighting; he has to understand each spirit, figuring out its shape, the story behind its existence, and why it’s causing trouble. And visually? Forget everything you’ve seen.

‘Serial Experiments Lain’ (1998)

I started watching ‘Serial Experiments Lain’ because I was drawn to the story of Lain Iwakura, a really quiet girl who gets super into this massive online network called the Wired. It’s amazing how the show makes you question what’s real and what’s not, especially as Lain gets more and more connected. It really hit on things that feel so relevant today – how technology affects who we are and how we connect with others.
