In The Heights is an adaptation of Lin-Manuel Miranda’s smash-hit stage musical — the one he wrote before Hamilton — and it is all-singing, all-dancing, and a ‘feelgood summer movie’, as they say. True, the storytelling is quite basic — anyone frowning over a calculator is sure to have money worries — and by the end of two and a half hours you may well be praying for less singing, and less dancing, I beg you.
