Why is that some anime anthology films are cancelled? I’ve seen Robot Carnival and Memories. I never saw but heard of Neo Tokyo, Short Peace or many others. Which leads to Twilight Q, an anthology series that lasted for two episodes. Why is that some kind of these films gets cancelled. What might be the reasons?
Most likely low sales. It's also an OVA so there is no such thing as committing to the episode count like a TV series. They can drop it at any episode if they deem the sales are low.
