Too Faithful to the book
I think the movie was going to be a massive success because of the popularity of the books , but I wonder if the books weren't a phenomenon if the 1st movie would have done so well.
There is such a thing as being too faithful to a book to the point that it sucks the life out of the adaption. HPSS is so concerned with fitting the book in that it feels like a highlight reel of the book. Columbus is an average director with not much visual flair and this movie shows how inexperienced he is with this type of movie. The POV shot when the trio see Fluffy looks like it belongs in Home Alone. Most of the visual effects are poor for a production this size, the troll, Neville riding the broom and let's not mention the quiditch match. It looks like someone painted a tarp of the quiditch background and the actors performed in front of it.
Now it's not all bad, Columbus and the team get credit for visualizing Hogwarts and casting the kids who ended up being pretty good.
I know some people wanted to Columbus to direct them all ,but I don't think he honestly would have had the skills to pull off the remaining books.
