They brought Barry Allen back once, but it turned out to be an alternate universe. 😛
Wait a second... I think I might've just figured out where Winick is taking the Jason Todd return... Infinite Crisis coming up, Crisis on Infinite Earths dealt with... well... way too many alternate realities... Flash was doing quite a bit with alternate universes before I dropped the title a year and a half ago (due to finances, I had to drop about 2/3 of what I was buying. That's one of the books I'll be filling in at the next big convention I can get to). Hal Jordan, Oliver Queen, Donna Troy, Jason Todd... Not to mention several villians that have come back from the dead...
Back on topic...
As just a movie, I thought Batman Begins was on par with Burton's two Bat-films. IMHO, Mask of the Phantasm remains the best Batman movie.
As a comic-book-movie, however, Batman Begins blew away all previous attempts. I can name everything I didn't like about it (as a comic geek); Ras never called Batman "Detective" (though hopefully that will happen in a sequel); Jim Gordon is supossed to have been a Seargent in Chicago when Bruce Wayne's parents were killed, so he shouldn't have been the detective on the case in Gotham; and Bruce Wayne is NOT supossed to know that Lucius Fox knows he's Batman. (Well, that and wouldn't the microwave transmitter have evaporated the water in everyone's bodies as well?) Now, if those are the only nit-picks a Batman comic book fanatic like me can make after seeing it twice, then they definitley managed to pull it off. Granted, in the current (post-Crisis) mythos, Batman never found out who killed his parents, but Joe Chill came from the pre-Crisis stories. (Untold Legend of the Batman contains just about everything the movie used that didn't come from post-Crisis continuity.)
