Great book. 

Decent movie.  I would have preferred if the movie were set in the Boston area (as the book was).  And I really wish they had not filmed an early-1980s airport scene at JFK's brand new terminal 4. That just threw me off.  Also, unlike in the book, there movie has a bit of trouble getting aging and timing correct (the time since Ashima's arrival in the US is not enough to have kids grow up quite as much).
