Although I would like to see a new (yet still very faithful) take on the series, what do you think will be the biggest hurdle for them?I think the casting will be incredibly hard to top. Casting Harry, obviously, will be immensely hard. Hermione, too, since Emma was perfect for her and strikingly similar even in person. Rupert is very easily replaceable to me. Looks ugly. But the adult cast will be so hard to top. Alan Rickman as Snape, Maggie Smith as McGonagall, etc.But there are also scenes that are so perfect and not in the books that it will be tough to live up to them. For instance, scenes like Harry/Hermione dancing, Slughorn's story, Malfoy in the RoR, the force field + statues protection, Buckbeak's flight, In Noctem, etc will be impossible to top.
