Goyer and Wesley should both be praised for what they did for Blade, something the people at Marvel have failed to replicate so far. That being said, I don't think we should get so caught up on Goyer and even Wesley's take on the character and be unwilling to accept someone else taking a crack at it. I would like to see more complexity with Blade and his world, while respecting the roots that Goyer and Wesley laid down.
To me Christopher Reeve is the definitive Superman, but that doesn't mean that I didn't think Gerard Christopher, Tom Welling, and even Dean Cain and Brandon Routh haven't done passable to great jobs with essentially the same character. The same with the Batmen-except Clooney- and all the Hulks and the last two Punishers.
I think Blade is an interesting enough character, a big enough character to survive different interpretations on him. Goyer and Snipes made him cool an showed the potential. But they weren't perfect. I would like to see if someone else could build on what Goyer and Snipes started.
