I must say it's nice, but it would've been pleasant to see the 'I ain't that good.' scene included instead of 'Good. Bad. I'm the guy with the gun.'
I mean, come on...
There was a lot of consideration that went into what lines to use. For this particular instance, I chose "Good. Bad. I'm the guy with the gun." because it's a fan favorite (at least for those who grew up with the U.S. Theatrical Version) and because Sam Raimi himself said he preferred it.
