I've been mostly staying away from message boards and the like for awhile. But I recently looked for a few reactions for Rebirth. I came across a complaint I'm not sure I understand.
To paraphrase what it basically boiled down to: "It was way too obvious that Jason Todd wants Batman to be his dad instead of a mentor."
...I'm confused because the basic premise of the Robins is that their Bruce's kids. That's usually been a huge part of the idea. (*1) Out of the first three Robins it's always been especially apparent for Jason (Post-Crisis) as he lacked a good father figure. Either because his dad was usually in jail or another version has Willis being an ass. So Bruce taking him in has always been a big deal for him.
While RHATO makes that relationship apparent it's pretty subtle compared to something like Justice League #19 (which I enjoyed) that literally has Jason voicing his doubts on being a son vs. "just another Robin" to Alfred. I think the closest this volume of RHATO has gotten to stating it has been the Fathers and Sons arc title and Jason starting to say Bruce was the closest thing he had to a father before he stops himself.
Their friction is being explored but I never got the impression that Bruce only sees Jason as a trainee while Jason views him as a parent.
And even if it was obvious why is that a bad thing?
*1 Which was a problem I had with Stephanie Brown being Robin (outside her treatment) since that closeness isn't quite there. Arguable for other interactions they had.
