Thank. God.
People don't care that this was scheduled or that Pokemon still sells. A boring demo is a boring demo no matter which way you cut it. You tell people to tune in at X time, especially when they make it clear pretty much the entirety of E3 will be for Zelda, showing one trailer and then going "ok Pokemon guys! Here's a boring demo!" for upwards of half an hour is terrible pacing even if this is how they do Treehouses.
We learned a lot of little things from that demo and it gave us some interesting questions to discuss, so I for one was happy with it.
