Alle land har sine krigshelter. I Danmark ble to av dem kalt Flammen og Citronen. Filmen om dem heter det samme og er imponerende, spennende og storslagen!
Abeel praised how, by "[a]voiding the docu-style string of anecdotes of many fact-based films, it offers the shapeliness and irony of classic drama". Hammond commended Madsen as the film "achieves a sense of psychological complexity – and a pervasive atmosphere of fear and confusion – without sacrificing the rhythm and dramatic tension necessary to a war film". of praised its combination of "sharp scenes of moral inquiry with a few too many functional, oldfangled espionage twists". Fuchs applauded the interpolation of emotional relations as they "help to make s taut action even more effective. Beautifully choreographed and filmed in deep shadows that cut the violence into shadowy, brutal fragments, Flame and Citron's jobs are at once thrilling and disconcerting". Kate Taylor from , however, said the romantic relationship, "predictable in a James Bond kind of way, is the weakest link in the script".
