Hate to bump this, but I am a massive Freddy fan and I'm very excited for this movie.
From the trailer, Freddy seems much darker.
In the first movie Freddy was silly in an insane way, like the Joker. The second one had him more aggressive. The rest had him more like a comedian and it worked best in Freddy vs Jason where he was actually funny.
I accept that Robert isn't playing him. From what I've seen so far, Earle's doing a good job.
NOW...they seem to be changing things a bit. Notice how when they're chasing him he screams, "I DIDN'T DO ANYTHING!!!". Is he being wrongfully accused in this one or is he not SO evil as he was during the trial in the Freddy's Nightmares tv show, Nightmare 6 and Freddy vs Jason when they show him getting burned?
In the remake, his makeup is much more realistic to what massive burn victims look like. He looks like he has melted. The only problem is, that's what burn victims look like when they HEAL! Part 1's makeup had the look of a fresh burn where the flesh is still falling off the face.
Nancy's father, Lt. Thompson, is not in the movie. Why remove such a pivotal character?
I also noticed that they seemed to have added things from parts 2 and 3.
In conclusion, I can't wait. Seeing as I can watch and enjoy part 5, they could basically do anything with the exception of New Nightmare and I will probably love it.
