Blimey, films are a funny thing. You couldn't ever use 'bleak, washed out sense of hopelessness' as a positive in a review many other things:
A restaurant. 'The moribund potatoes were a delight'
A creche. 'The sense of forlorn loss on the faces of the children present was greatly entertaining'
A massage parlour. 'Concluding with a very unhappy ending. Five stars'
A holiday camp. 'Vorhees was nothing if not attentive, ensuring that each attendee was run through with the machete at least once per day'
