Very dark and mysterious film that interweaves a relationship between two neighbors, and a present day investigation. The screenplay is pondersome, and yet deliberate, in feeding (pardon the pun) the viewer certain amounts of information at a time. We get to know the characters, and exceptionally so, their quirks. The atmosphere is very dark, and claustrophobic, which adds so much to the film. The memories are haunting. It would be very hard not to talk about this movie after viewing it. Creepy, and at times, rather darkly funny, 301/302 is an offbeat choice very worthy of your consideration. Recommended.
