This film is one half of the Duel Project, the result of a drunken challenge between two famous Japanese directors. In making their films, they had a set of rules to abide:
1. Only 2-3 characters.
2. The entirety of the film must take place in one set.
3. The two lead characters must fight to the death.
4. Must be shot in seven days.
The tension between the two girls in 2LDK builds perfectly, and by the time they get to fighting, it seems perfectly reasonable for them to fight to the death. However, the pacing of the fights seemed a little off to me. Too much stopping, kills the momentum a little.
Whereas the characters in Aragami were somewhat 2-dimensional, the main characters in 2LDK have more depth and personality.
Both films stretched the rules of the Duel Project, but 2LDK followed them closer, only using supporting characters in hallucinations, phone calls and photographs.
Both films have distinctly different styles and tones, and both are good in their own way. Because of this, it is hard to necessarily call one "better" than the other-- so in order to make my decision of who won, I have to look at which film followed the rules closer. Therefore:
MY PICK FOR WINNER OF THE DUEL PROJECT: 2LDK
