The film was great until nearer to they end, they went to far. There was an unneeded ‘plot twist’ which made me, as an adult, feel sick. I like dark movies, scary movies even, but this film crosses a line with animals and babies alike and has an unwanted psychological impact. If you want to feel bad for weeks, then this might be the film for you, but if you don’t like disturbing images which are hard to remove from your head, i’d suggest avoiding.
The main problem i had is that they made their point earlier on, they want you to hate a character, but the character was already hated, by adding a scene they made me personally hate the film and the director, which usually isn’t something a film aims for.
