I did not have very high hopes for this one (a German slasher movie? "Anatomie" was quite good but I never heard of "Flashback" before...) But Flashback was actually a pleasant surprise! It is rather gory and has certainly earned its FSK 18 classification, but it is also quite clever, thrilling and has just the right small dose of humor. The story has some interesting twists and turns and I was glued to the screen throughout the whole movie. More of this, please!
