I see what you're saying, but I think its probably difficult to decide where to draw the line. No matter how much or little we're given when it comes to Hogwarts in specific, we'll always want more. This is because we've seen and read about every nook and cranny of this castle, and damn it, we want to see it all! I would've loved to see some moving staircases, the Great Hall, or the Potions classroom in the FJ queue, simply because those locations were so memorable and significant in the source material. Alas, limitations must be set due to the reality that we live in. Only so much can be done in the real world. There are a lot more things I would have liked to see in Hogwarts, but at the end of the day, what we have is pretty incredible (just my opinion).
