I don't get superlatives like 'worst' and 'ever'.

The story involves the relationship period Frances Bacon (Jacobi) spent with his tragically unbalanced partner, George Dyer (a pensive portrayal by Daniel Craig). The film includes several well-acted social vignettes (such as bar conversation scenes) that serve as its narrative of sorts.

Interspersed in the movie are montages showing a variety of provocative images derived of the couple's rough sexual acts, various fantasy sequences, as well as images of violence - all of which are seen as apparent influences on Bacon's artworks.

On an odd note: In the bar scenes Tilda Swinton (one of the bar regulars, Muriel) is nearly unrecognizable with her prosthetic Quasimoto teeth. The British seem to enjoy their caricatures of people with awful teeth or of dreadful stutterers. Swinton's camera shots are blurred and brief (I suspect to temper the teeth upstaging her scenes).

This movie has somewhat of a Warhol vibe to it, except these characters are more in-your-face coarse and loathsomely rude. Overall the movie is a stark portrait of the rough fringes of human behavior when minds are influenced by drugs, alcohol, money, and mutually accepted moratorium on social boundaries. All of this, I suppose, is intended to give insight into the artist.

This film can't be "the worst ever" because there are yet other films to come. I found this film to be a memorable and rather insightful interpretation of a sensational artist's world from the inside. You don't see bold "art films" like this very often. Low budget ones rarely succeed. This one gets away with it nicely.
