What's your hot take on Berserk?

I'm caught up with the manga so there will be spoilers ahead on what I'm about to say. I love the story but man I was a bit disappointed with how long it took for Casca to recover most of her trauma/memories back. She was a strong and powerful female character and then she eventually regressed back into a child-like low IQ state for way too long. I felt like it was unnecessarily long to encompass her into that type of state - especially when she held a lot of power and was a master sword-wielder.
