Can you believe it? The Batman saga is over. Yeah, there will be another Batman movie (that's inevitable), but Christopher Nolan's Dark Knight saga is finished. Never again will we see Christian Bale don the cowl, or Gary Oldman don the mustache (both of equal importance). Yes, it feels horrible, doesn't it? Well, imagine if you were Christopher Nolan. On the one hand, finishing The Dark Knight saga leaves the director open for a bounty of new opportunities, something he would have probably never have if he didn't tackle Batman Begins. He can do anything he wants at this point. Yet, Nolan devoted about half a decade to this saga, and now his work is complete. Apparently, the director felt that a proper good bye was in order. And he gave the franchise just that. Check out the very heartfelt goodbye letter Christopher Nolan wrote to the Batman saga below.
