It took me a while to decide whether I liked it or not. I guess it's one of those movies that are just... fine. I don't feel like I wasted my time but it didn't leave me thinking "what a great movie" either.
De uskyldige (The Innocents) is an atmospheric, nicely shot slow burner that ultimately fails to justify its demanding 117-minute running time. The first half is quite slow, with little narrative substance and virtually no dialogue - just children being mean and creepy - so that by the end of the first hour it begins to drag. The pace eventually picks up over the last 40 minutes, which are delightfully tense and suspenseful and manage to keep you on the edge of your seat with some great spooky (and gruesome) scenes, but at this point it feels like too little too late. Nice cinematography and sound that enhance the eerie overtone of the movie; the kids' acting is excellent.
Overall, a nice suspense/supernatural flick with a nordic vibe going on (one can't help but think of von Trier's similar nordic oddity Riget). I just think it could have used a bit more plot and a shorter runtime.
