We've talked about retcons we liked, and retcons we disliked. But what about recons that just didn't really matter? Maybe at first it looked like your chosen retcon would make a difference, but then the plotline fizzled out. Maybe it was just a cover for a previous continuity blunder. Whatever. The question are which retcons do you think ultimately amounted to nothing?

For me, top place is probably taken by Barbara Gordon being Jim Gordon's niece. Or maybe his biological daughter from a liaison with his brother's wife. While I can't say I've read Jim or Barbara extensively in the era immediately after either reveal, neither of these seemed to have actually changed anything, and both seem useless. Probably why they don't exist anymore. Probably followed up closely by Tony Gordon being brought back in the bronze age only to be killed off (or disappear again if not really dead - not sure we saw actual death or body).
