"Remember, though, that this is a film - it is a construction". Well duh! This clunky superfluous reminder suits the film perfectly. Sometimes these clever reality warp films work, and sometimes (as here) they don't. Why? Firstly, the intense love needs to be better realised (e.g. Eternal Sunshine of the Spotless Mind). Here the main character is unsympathetically self-absorbed and treats his girlfriend like a doormat; worse, his encounters with the mystery femme fatale have the profundity of a lager ad.
Secondly, the reality warp needs to create tension and direction (e.g. Memento, with which this film claims to be compared). In Reconstruction the love object's partner is a novelist who is writing, and thus er "Constructing" (ding! ding!) the events of the film. Unfortunately this undermines the reality of the characters. A film can warp reality as much as it likes provided we can still believe in the characters, and care for their predicaments.
The acting is first class and many familiar faces (Krister Henriksson: Wallander)and others from The Killing remind this viewer how badly it compares with the brilliant stuff currently gushing out of Sweden, Norway and Denmark.
