I chanced upon The Book of Love while channel-switching, saw Maisie Williams, looked for the repeat and watched it. I very nearly didn't because the synopsis made it look like a Hallmark production (bereaved architect heals himself by helping troubled teenager build a raft to sail round the world) but I thought, "What the hell, it's Arya" and watched it. I'm glad I did, because although it contains a slew of "heartwarming" clichés, it plays around with them in a very quirky way, to the extent that it's almost but not quite a satire on the genre. But there's more than playing around with clichés: the relationship between the two main characters is lovely, and there are some thought-provoking moments, though it's easy to skip over them.
