No, Grace, not his fault...
So, this series had its #MeToo moment with Grace confessing to her dad that his good friend molested her at 15 while she was working for him. Okay, so far, so good...
... until ...
... she blames her father -- and then nobly forgives him -- for not protecting her.
Wut? She didn't tell her father for decades after the incident. How was he supposed to know? Sorry, Grace, your father isn't to blame for what happened to you.
If there was any failing on the part of her father, it was for raising a dim-witted daughter who kept a secret about a predator for decades, possibly leaving other women/girls at his mercy.
Now, THAT would have been a powerful episode. In flashback, we could have seen Grace bravely ratting out the predator decades earlier, leading to a rift between her and her father who refuses to believe her.
Then, in the present, we could have seen the father finally apologizing for not believing her and encouraging her when she first reported it.
As written, the episode simply made the both of them out to be stupid.
