Query: Unsubstantial flash

It was very disappointing to see major actors, cinematographers, and editors doing a good job with decidedly sub-rate material. The film looks much, much better than its story. One begins to have doubts when this family of "geniuses" reveal little intellectual heft in conversation and interaction. The Paltrow character is a virtual cipher whose only talent seems to be finding stashes for her cigarettes, despite her promotion as a "prodigy". The purported love triangle has no apparent basis, in other words, the audience is told to accept the premise without evidence. The problem is that this film was written by people who are not professional, creative writers. Characters must be shown to be "interesting", "conflicted", "in-love", "suicidal", etc. by their words and actions, not simply because we are told they are. This can only be accomplished by subtle and clever writing, which is wholly absent here.
