Endlessly ambitious The Tree of Life loses the grip from time to time though, making an impression that the author uses the tools of the greats (like cinematography style of Tarkovsky) for the sake of tools and not for the movie's. The grandeur of the ideas, the courage of Malick, including the evolution sequences and the performances (especially Pitt's) on the other hand give the film the needed air and depth.
Uncomfortably straight and honest at times the film is an unusual (for a contemporary mass audience targeted movie) glance at a psychological comedy-slash-thriller. Unique and captivating, although unsettling.
Though a brave effort to speak loudly on a theme, which is usually concerned a tabu, the film's creative side leaves much to be desired. The humour is quite plain, the performances are not impressive (excluding Park) and overall the movie is pretty unnecessary.
