LOL. You don't know them, don't judge. They are fully grown adults, read every book, watched every movie, two even read the book this is based off of. They're just skeptical at this juncture on how it will play out and if it will be entertaining enough beyond showing off what they can do with special effects, dragons, etc. If this turns out to be a not so good movie, the consensus was it would ruin how they look at the Potter series in general.
