Re-doing Blade would be difficult. Snipes DID own that role... literally. He re-invented the character in that film series, it even carried through to the comics. Before then Blade was basically Luke Cage who hunted vampires.
He may not have had many lines, but he just had this intangible swagger and attitude. Blade is Snipes, not the other way around.
Exactly and you can't forget a lot of the other attributes Snipes brought to Blade such as designing the weapons and Blade's fighting style (which isn't just your typical martial arts style) etc. Also Snipes rejecting to do some things that Goyer wrote on page saying that's something Blade wouldn't do. Seems like Snipes contributions to the character always get overlooked while Goyer get's heavy praise on the internet.
