Shiver is a story of a boy who suffers from photo phobia which forces him to move to a location with less sunlight & shorter days,unfortunately this place also hides something very terrifying and so the real story begins.The film was good with a some really terrifying sequences and an interesting story.It makes you feel like watching the Swedish masterpiece 'LET THE RIGHT ONE IN' in a different way,but the films differ very much on many grounds and i am sure that many would agree.Many of my friends who have seen it believe its the best Spanish horror flick of all time,i believe a horror fan(&otherwise also)should never miss such an interesting film which now has prompted me to search for other Spanish thriller/horror movies...definitely better than your average horror flick...
