glad to see the Blu-ray is doing so well. I really could not care less about the Extended Cut or not. This version is a perfectly paced movie that has only a few minor flaws and is extremely entertaining. It comes with a Director's commentary (a must), plus a 2-hour making-of documentary. Not much else is needed, IMO....
But if the DVD/Blu-ray continues to sell this well through the rest of the year, then the likelihood of Kick-Ass 2 the movie is much higher. And while it doesn't really need a sequel, more Hit-Girl and Red Mist will be awesome. And while Millar is writing it either way, I much prefer Vaughn's take on the characters and story to Millar's, so I'm glad it is doing so well.
