You're right, 'generic' was the wrong word. I think it was, rather, too obvious
. Like we should have been able to read all that just from seeing the determination in Batman's face. We had all the context already.
It didn't need to be said, just like 'So that's how that feels' didn't need to be said - well, maybe less so than that example.
In short: Silence can sometimes be more powerful and emotive than a one-liner.
The movie, for me, had a recurring problem with over-explaining the wrong things while not better explaining other things that needed it.
