Probably due to my love of "alternate histories/alternate dimensions", I'm really stoked about the concept behind Flashpoint. Especially so since this is, as far as I know, the first time DC has EVER done something like this. The concept is almost old-hat at Marvle Comics, with stuff like "Age of Apocalypse", "House of M", and the recent "Age of X" stuff. But as far as I know... this is a pretty new concept at DC Comics. Sure we've seen self-contained "alternate earth/rewritten reality" scenarios in countless DC Comics stories, not to mention they practically BIRTHED the concept of a comic multiverse... but not something like this... where there's more than one comic series tying into it, not to this magnitude. 
 
So I'm looking forward to seeing how this plays out.
