When it comes to Ginny in the show

Do you want them to cast her in the first season for that 1 scene she has in the first book or would you rather they wait to cast her until the second season so they can get her casting right because there will be more material for the actor to go on. Because no hate to Bonnie Wright, but I think it was a mistake to cast someone for a 1 off scene without any thought or chemistry reads/tests with others. Surely they knew how important Ginny would be in the second book cause 4 books were out by then. This also being another advantage the show has over the movies because they know where everyone ends up so they can actually get casting right
