Enter Mr Citrus Man is a four-handed, heavy-handed parable that struggles to rise above easy caricatures and ends with a hopeful message about love and safety that is weakened by its reliance on simplistic characterisation. A couple live in innocent harmony when the Citrus Man comes along and steals away the woman with promises of fulfilment but is rapidly revealed as a self-serving liar. 

The bright set and sinister presence of the Citrus Man lend this production charm and threat, but a lack of depth to the emotions on display is more alienating than intriguing. The measured pace and uneven performances battle with a script that, while never falling into cliché, reduces their parable to the childlike. The appearance of a puppet is an amusing interlude, but adds little to the drama and, while not quite comedic, this production lacks the necessary tension to express its message with dynamism.
