Concorde was a great aircraft and an impressive engineering success. It offered a lot but was beset with numerous problems from conception throughout its lifecycle. High operating costs, supersonic safety perceptions, and noise pollution restrictions hampered its success. Ultimately, it was retired, as were supersonic passenger flights until very recently. Its high fuel use was undoubtedly a factor in its eventual shelving.
