Four and a half. A bit slowing moving at first but once you dive into the relationships and characters more deeply the movie picks up tremendously. Top notch acting throughout and just a compelling piece of drama about a taboo subject that's handled beautifully. Nothing camp or overtly political about this film but that in and of itself makes the film an even more powerful social-political-relevant statement.
Perhaps the most interesting look at swinging London in the early 1970s I can recall. For younger audiences, it may not be believable that a woman would have no problem with her lover having an affair with a male doctor. This is swinging London during a sexually liberated period after all.
An honest study of absence and compromise, in other words: life. The ongoing notion of 'is half a loaf better than none?' permeates with stunted communication, no commitment and certainly no love. Superb performances by Jackson and Finch (Head come off a unfair third in a cypher of a role) are enhanced by the wealth of counterpoint circumstantial detail that provides visual illustration, not just decoration. Sublime.
