A virtual remake of the truly scarey highly imaginative 1980s film about a bunch of teenagers who must stay awake as the nightmare figure, old pizza face Freddie Kreuger, in their dreams kills them in their sleep.
If you haven't seen the original, or even the whole series, then that's what you should be watching (bar, possibly, 'Nightmare on Elm Street 2') rather than this high production, but soulless, rehash.
