One expects that, watching the Harry Potter movies with his kids, assuming the day comes, will be a pretty great experience.
Whether or not they like their dad as much when they see what Draco Malfoy does to Harry Potter is also interesting to consider.
Whether or not the kids actually believe the blonde-haired jerk is actually their dad is an open question.
Kids almost always love every movie they see, which means they’ll probably adore something like the Wizarding World films, especially the first couple, which are very family friendly and full of magic.
