Who didn’t see that one coming? ABC’s midseason drama Happy Town is headed for a quick exit. The network will air the show’s third episode on Wednesday as planned, but will preempt it next week with Primetime: What Would You Do? which did solid numbers on Friday. Telecast of Transformers was already scheduled for the 26th, and then Happy Town will return on June 2 with the remaining five episodes. In its second airing last week, the mystery drama (1.2 rating/4 share among adults 18-49, 3.9 million viewers overall) dropped 29% in the 18-49 demo from its disappointing premiere.
