A difficult call. On the one hand: a worthy subject matter; mobile prison grille set with different tableaus sliding from underneath the frame; Lesley Manville's lovely upper-class English voice and National Theatre's wondrous £10 ticket scheme. On the other hand: independent and scattered vignettes rather than a storyline; a lesbian affair lacking chemistry and credibility and a very slow-moving second half. In the end, I lean slightly towards HOT if only because it gave me appreciation, however shallow, of the intense strength of will of the suffragettes and made me resolve to not take for granted my right to vote.
NB To the sweaty-hoofed person sitting somewhere behind me - keep your nauseating smelly shoes on next time!
