See it if you enjoy Ayckbourn's wacky plots, humorous situations and truthful ironies. His characterizations are comic and the actors do him proud.
Don't see it if you are in a morose mood, not into being entertained with laughter and despise British acting and humor.
See it if you like romantic, light-hearted diversions about real people bahving in silly but charming ways.
Don't see it if you can't invest three nights at the theatre, since the play is three plays in one, each set in a different part of the same house & garden.
