The phrase "glowing reviews" refers to positive feedback or praise that is given in a highly enthusiastic and complimentary manner. It implies that the person giving the review had such an excellent experience with something, whether it be a product, service, event, or performance, that they are extremely impressed and cannot stop talking about how great it was. The term "glowing" suggests that the praise is so strong and effusive that it seems to radiate warmth and positivity, much like a glowing ember in a fire.
