Despite massive zombie hordes and alternate realities, "The Walking Dead's" midseason premiere and "The Flash's" conclusion to its Earth-2 adventure weren't able to maintain their respective audiences, though both shows continued to enjoy impressive numbers.

According to Entertainment Weekly, "No Way Out" -- "The Walking Dead's" Sunday night return -- dipped 12% from last year's midseason premiere. Additionally, viewership fell to 13.7 million from the midseason finale's 18.3 million. Still, the numbers are nothing to scoff at; the show nabbed a 6.8 rating among adults 18-49, which is the highest adult demo rating for a scripted series this year.
