Roy Lichtenstein at the Hayward Gallery

Roy Lichtenstein's style is simple; a collection of dots and thick lines make up the scenes that he used to comment on popular culture, particularly American culture. Perhaps what's so pleasing about his work is its simplicity and boldness. This look is achieved by his main usage of the primary colours and black.

His themes are overt and understandable ranging from World War II to relationships between lusty blondes and handsome dark haired men. Other works aren't as complex—a ball of twine, a single paint stroke; he enlarges the imperfect reality of life with his almost perfect painting techniques.

The gallery facilitates the collection well with short films that run continually about Lichtenstein's reflections, and his work in London. In a sentence, the collection is brilliant and an excellent way to spend an afternoon.

• Roy Lichtenstein is at the South Bank Centre's Hayward Gallery until Sunday 16 May; daily 11am-7pm (Tue & Wed 8pm; Fri 9pm); admission £8 (conc £6).
