Let's get it straight first off: I am a big fan of Lynch's and I know that this is supposed to be a long ad.
But that does not stop me from thinking that this short film is a ludicrous effort that only serves the purpose of reminding the viewer how great Lynch used to be, at least up to Mulholland Dr., which is now more than ten years ago! Everything, maybe except for the music, is wrong in this short. As usual the plot makes no sense at all, which could be bearable in itself, but no atmosphere is built out of the plot less story either, so the fact that there is no or little story does become a problem. Second, the Chinese actors are terrible, they are so bad that it looks like Lynch cast the first two guys he saw walking down the street. On we go. The bag as mysterious, symptomatic object (see blue box from Mulholland Dr.) is used in a ridiculous way, both when it is seen in the hotel room and on the billboard. Cotillard tries hard but there is little to do with a character that has to deliver useless "I love you" lines to a random Chinese guy waving a blue napkin (or was it a rose).
Finally a word on the digital video cameras. I already disliked Inland Empire because it used them. I think Lynch should abandon this idea and go back to a more traditional technique. The sexiness of movies such as Mulholland and Lost Highway was also due to the fantastic way they were photographed. We do not need the shakiness and the low resolution of Inland Empire and of this short, they just don't add anything while they take away a lot.
Now, Mr Lynch, please go back to make feature films and return to your old standards, we are tired of pointless digital video shorts.
