For a gift my mother bought me tickets to the Cursed Child play, which is coming to SF this fall.
I had never read the books or seen the movies so I figured it was time pick them up from the library and see what the deal was with the cultural phenomenon I basically bypassed.
I'm through the first three books. I can now see why people like them. They are well done, entertaining, and super accessible. While they won't go on my list of favorite books they have been more than good enough for me to finish the series.
