My parents have never read the books or seen the movies and really know nothing except that it's about magic - would they be able to follow the plot? I think they'd really love the spectacle of it, and they like seeing the hot showof the moment, but I don't want to waste anyone's money if they'd be clueless. Thanks!
(All assuming I'm lucky enough to get an access code, of course.)"
Theoretically, yes, they could see the show and understand what's going on. The London program has a detailed synopsis of each book in it, with key characters that make an appearance in the play highlighted (I'm assuming Bway will do similar.) The play is written for people vaguely familiar to understand it, which is why when reading it, it reads like fan fiction. On stage, it all makes sense as they're laying out context that is necessary unless every audience member was a superfan. I imagine this was for longevity's sake - eventually 5-10 years into the plays run, people less and less familiar with Harry Potter will see it.
Of course, this is all coming from a superfan, who was disappointed in the initial script, but was completely floored when I saw the production in person. It definitely has something for everyone. It's kind of like if Hamilton was only appropriate to US History buffs.
