90 minutes approx, no interval. Billed as a version of Euripides with Brazilian capoeiro -- a kind of dance-cum-martial arts discipline, apparently.
Missed it: had to work. Child One went in my place.
S hated it. Says she fell asleep three times and awoke each time to realise with horror that it hadn't yet finished. D rather enjoyed it but found the plotting confused: she had to consult Child One (a student of classical civilisation) afterwards for clarification.
Child One liked it too and has promised a review. Don't hold your breath.
