Naoki Urasawa

[Papasmurf]

Most of Urasawa's works have bad endings tbh. Pluto was weak all the way through and I could barely remember who the "final antagonist" in 20th/21st Century Boys even was.

Monster is great but the ending frustrated me.

Without spoiling the ending, I feel like it was a good ending, as it kept the protagonist true to himself.

If I know who Johan is, is it worth reading/watching?

 

[Yoshi]

Yes, because it’s spoiled in the very beginning.

If I know who Johan is, is it worth reading/watching?

Yes of course. It's the best manga ever written.
