Many have a book that make them want to bury it under a mountain of newspapers and hug it at the same time. Arcadia came very close to that for me. This play made me want to tear my hair out at erroneous historical representation of science and at the same time made me giggle at the obnoxiousness of (some of) the characters. 
 I have struggled with Stoppard's writing before. I believe his writing is poignant and does a systemic throwbacks at different literature and artists like a ginormous inside joke. Because I didn't get it. For example - why such disregard towards Newtonian physics? 
 Arcadia tries to balance itself in the grey area that separates romanticism and enlightenment era. A character says: 
 "It's the best possible time of being alive, when almost everything you thought you knew is wrong." 
 This is a disconcerting thought. Science is continually evolving and naturally it improvises over time. To brush off everything that has gone into be what it is today makes the character seem disingenuous and trifle with the heart of the play. 
 It is an enjoyable play that tinkers with handful of themes and paints them as juxtapositions: attraction between tutor and student, arts and science, time and effort etc. 
 Oh, there is waltz at the end of the world :-) Tom Stoppard says so!
