Not for everyone... definitely only for pro viewers, this movie stand with movies like mother & Mulholland drive. I think this movie was great,what you seeing in the film & what the meaning of the movie is completely different. Its not linear, simple movie. If your are action,rom-com movie fan then its not for you. This movie is only for very particular passionate pro level audience. Just like david lynch took duality concept to whole mindbending way in Mulholland drive, Charlie Kaufman took regret to next level filmmaking. Once you know the answers,you will appreciate it.
By the way,its jack that you want to keep your eye on not lucia, answers are not there where you looking it,its buried deep within artistic symbolic & metaphoric approach of Charlie Kaufman.
Still i have to find one negative that it will be the runtime, i thing this movie could have been worked better in about 1&half hour time.
