This is why I'll never fully understand how Selina "settled down" with Bruce. If anything as a love interest she's more suited to a "Batman Continues"-esque ending. Don't get me wrong the scene itself was nice and I would have hated for Bruce to be Batman forever but I don't think her character really works with that kind of ending as Catwoman is supposed to represent the side of Bruce that wants to be Batman imo.
It's an example of how with TDKR it felt to me like they were just throwing in a lot of ideas, even if some were ultimately incompatible with one another which makes the film as a whole sum feel awkward to me.
