Like virtually every horror fan-- and especially us 1980's kids-- this trailer has been THE most anticipaed thing since maybe the Texas Chainsaw Massacre remake trailer and I think even more than that. Freddy Krueger seemed to be the one horror villain that everyone was really nervous about being re-created.
I personally think that Jackie Earle Haley will do a good job as Freddy and that according to the trailer he pretty much nailed Freddy. The trailer looked good though- looks like it has that atmosphere that A Nightmare On Elm Street 1 and 2 had, which pretty much all but dissipated after (maybe) Part 3 or 4. The look of Freddy is 50/50-- he now looks like a legitimate burn victim, something he old Freddy did not. Jackie's speech as Freddy was also accurate as a burn victim even though it does sound a lot like he's trying to be Robert Englund too hard.
All in all, I dug the trailer and I have a feeling that this movie is going to make a shit-ton of money.
