"$400 that's disgusting they won't get it if people refuse to pay it."
That's kind of the opposite of what happened. Premium seating exists because theater got tired of selling everyone regular priced tickets and then seeing people selling them for 2-4x more on eBay/StubHub, etc. So, they figured if anyone should get to sell the seats for more based on demand, why not them?
Now, a case could be made that paperless ticketing or some other option could have removed the scalping angle, but now that the genie is out of the bottle, and producers are seeing that money, forget it.
"Well, now I want to see Ezra Miller as Hedwig (even if he is too young.)"
I know, right? I want to see him in everything. He does have a band that plays around NYC, Sons of an Illustrious Father, if you ever get to see them. I haven't gone yet.
