I agree, not sure why they seem in such a rush to cut to the top 30. Even the judges talked like they were being rushed to narrow the field, but they didn't understand why. Seems in prior years they had various rounds, group performances and then narrowed the field down. Part of watching the competition is seeing a variety of performers both good and bad. Last night they tended to show those who were moving on.
I would think parents of some contestants who made it this far but are never shown on TV would be hugely disappointed. Seemed like there were already a lot of people in the golden room even when they supposedly announced the first set of finalists. My impression was only those moving on would be in that room. Likely they aren't showing the competition in the order it actually took place.
