The only reason I regret reading Berserk is because now no manga or anime even comes close to how good it is. It might act as a turn off to some younger viewers because of the violence, complex story line, sex (probably not), and tragedy.

Everything in this anime is perfect and might take a little difficulty to be appreciated because of its age.

It's original
The artwork is amazing
The story line is tragic and superb
It's the coolest and saddest thing you will ever read
