			Lastly, there was a repeating of lines. Difference is, not only was the execution by the actors superior in BR, but the circumstance didn't overtly come off as "superhero must tell something important to the damsel before he goes off in the night!"
		
		
	 
The identity revelation in Begins annoyed me because it seemed like an afterthought--Bruce says "Oh, I'm Batman," and then they talk about it for a minute at the end. It was used as a vehicle expose Batman as the dominant personality in Bruce's mind, but that had already been done, and could have been solidified in a better way. Rachel discovering his identity was mostly pointless.
In Batman Returns, the relationship was not only far more interesting, by the revelation of their identities was much better, with more honest and interesting reactions.
Selena was a kindred spirit, as much damaged goods as Bruce himself, and they were both aware of this long before they knew each other's identities. They fit together nicely. The line-repeating wasn't what made their discovery work, but rather the reactions they had when they figured it out. Selena's "Do we have to start fighting" line sounds a little childish, but it's an honest reaction. Bruce's suggestion of moving outside to talk about this rang true, too. More importantly, though, was when they met again in the sewers. Batman Returns is about the price of vengeance, and Bruce is appealing to Selena to leave vengeance behind, because it's something he's struggled with, himself. The difference, of course, is that Bruce wants to dig himself out of that hole, and Selena doesn't.
In Begins, what reaction did Bruce and Rachel have? Bruce just says "Oh, I'm Batman" and jumps off a roof. Then, later, they have a little talk, and even though they're dealing with some major issues, neither seems very affected. Also, the conversation was backwards: Bruce should have been the one telling Rachel they couldn't have a relationship. In the film, Bruce's admittance of being Batman feels almost as if he's trying to impress her because her low opinion of him hurt his feelings. The 
real reason should have been that Bruce wanted to show her why they couldn't be together, a moment of honesty to respect the relationship they used to have.  It should have been a moment where he decided she deserved more than lies, and an honest explanation of why there was no future for them, rather than a moment where he tried to prove his own worth.
Both B89 and BB deal with this idea of Bruce discovering that he can't have relationships with normal women while being Batman. I think B89 handled in a much more natural, truthful way, where as in Begins it seemed kind of forced. Even though in B89 they tried to make it work, the obvious implication when they spoke in the cave (before Bruce suits up) is that it's 
not going to work, and they're fooling themselves by trying.
Begins is the superior film, but Returns had 
easily the best relationship dynamic of any Batman film (except maybe Phantasm), and I'd say B89's relationship dynamic was better than BB's, too. 
I would have loved to see Burton's "Batman Forever." Everything is so miserable at the end of Returns; Bruce's life as Batman has brought him to the  absolute 
rock bottom. He's seen the what an obsession with vengeance did to Selena--and more importantly, the Penguin--and I expect a Burton-driven third film would have dealt with Bruce dealing with that obsessions in himself; leaving behind the killing and darker motivations we see in B89/BR. Schumacher's BF touched on this somewhat (With Bruce trying to teach Dick the consequences of murder), but it was marginalized and ruined by Bruce killing Dent at the end of the film (and also ruined by the sheer craptitude of the film).
