Julie Delpy is super annoying
I actually think that Delpy does not 'act' because she plays the same character in most of her films, concluding she is actually just playing herself! In 2 days in Paris, she was just as annoying, irrational, argumentative..she has a very annoying character and any man that has a relationship will ultimately go mad if he stays with her.
In saying that I did like how the film explored topics on relationships, love, the idea of a soulmate etc. but I just find Delpy utterly annoying.
