I'm from Spain so I've seen a lot of Spanish movies hehe.
Someone told you Who can kill a child? That's right, the film is absolutely awesome. The same director, Ibañez Serrador, made The house that screamed, amazing and one of my favourites.
Another good one is Day of the beast, directed by Alex de la Iglesia. I think you'll like it.
A recent one is The body, it's more like a thriller but there are some horror elements.
And if you want to have a really bad time, try to watch La cabina by Antonio Mercero. It's a 30 min. short but it's very popular in my country and everyboy was shocked 40 years ago when it was broadcasted.
There are more movies but the best ones have been listed by the rest of the people here.
