On one side i see the point and AGREE that Rnglund should return as the infamous Krueger. On the other hand, you didnt see the same guy who played Micheal Meyers in the Rob Zombie remake reprise his shatner mask either, and I found the newer Micheal to be more threatening honestly (but no one will ever replace the scream queen Jamie Lee Curtis, that tweeny bitch couldnt pull it off.)
It might be interesting to have Robert play more his pre-dream demon side in perhaps flashbacks and maybe even a REALLY BETTER REMADE burning to death scene (final nightmare DIE IN HELL!) and then have either him or someone who is REALLY good and exceptable to play a more horrifyingly demonic embelishment of Freddy in the dreams of the elm street children.
In my honest opinion I want Robert through and through, no question about it. I wouldnt mind a remake, as I agree with others here that no matter what you cant replace an original. Its become fused into our culture and their is no eracing it.
A complete overhaul could be okay, then again why mess with a successful story? Sure rob zombie fleshed out the meyers history to a better understanding for the newer generation and perhaps even the older generation, but the original plot of ANOES is what made it so successful.
Lets just wait and see what pops up in the future and go from there.
