My opinion is clearly a bit biased, as I was grown and raised on these films, but each holds a special place in my sadistic heart. Some entries, such as Freddy's Dead, haven't aged as well as I hoped they would. I used to love that flick as a kid. Others, like Freddy's Revenge, I've grown more fond of. Wes Craven's New Nightmare may be the smartest film in the entire series, but The Dream Master will always be my all time favorite film. The nostalgia that movie has is probably greater than anything else I possess. Pretty much sums up my favorite Horror series!
Edit: a nightmare on elm street (platinum dunes) : 0/10
This film was so bad on every level. Structurally it was a mess. There were no interesting characters. The acting sucked as well as the kills. Don't even get me started on how they butchered the characters of Freddy Krueger and Nancy Thompson. Just an awful, awful waste of celluloid.
