Tickets for “Day of the Doctor” went on sale two hours ago, and many locations are already sold out. We apologize for the late notice. Due to a somewhat bizarre comedy of errors, I was unable to sleep at home last night, postponing both this news and the “Agents of SHIELD” review. It appears I bought the last available ticket in Edmonton, Alberta about an hour ago. Rumours of additional locations opening up are flying, but I haven’t seen any such word from official sources.
