Ultimately, yes.
I would agree to give up BF, and B&R for Burton's third Batman film. The only reason I would even hesitate slightly, is because I do enjoy BF. As it is a much darker film than everyone gives it credit for being, but unfortunately it gets lumped right in there with B&R. However, as much as I like BF, I would be most willing to sacrifice the film in order to have a Burton Bat-Trilogy. Admittedly, "Batman 3" would be akin to Burton's Batman Returns which Burton had much creative control and direction over, which I'm sure would have caused some concern with a certain group of fans, but on the other hand Returns is liked by a very good majority of Batman fans, so that might not necessarly be a bad thing in of itself.
