It's probably a stretch to call this a "hit," as it actually got mixed reception in Cannes. The reaction was apparently very divisive, with some critics loving it and others hating it. It's a three hour epic about lost youth and from this trailer I can tell it's going to have a lot of montages of partying, drug use, etc. One of those. The director is Andrea Arnold though, who made one of my favorite films of the last decade, Fish Tank, so there may some good stuff mixed in there with the overindulgent.
