A four-star review is generally considered to be very positive and is often associated with words such as 'RAVE' and 'ACCOLADE'. RAVE is a four-letter word meaning to express great enthusiasm or admiration for something, while ACCOLADE is an eight-letter word meaning an expression of praise or admiration.
