*- For this winter's War of 18-49 updates, the A18-49+ is based on a projected league average, calculated by applying the league average's current year-to-year trend (thru 1/18/15) to the final 2013-14 average. This should help make these numbers compare more fairly with fall seasons past.
Rating the Ratings: It was a somewhat strange season for a franchise that seemed to have a lot of momentum coming into the season. The premiere's 2.4 rating was legitimately disappointing, down by 23% year-to-year despite getting a head start on the regular season competition. The show didn't drop as much as usual in the first few weeks of the regular season, but since the premiere had started it off in a hole, the numbers were still pretty soft (as low as 1.7 on a Monday and 1.6 for a special Tuesday show). The show caught a bit of a second wind in its return to a consistent 2.0 in October, perhaps benefiting from Gotham and The Voice coming back to earth and then The Big Bang Theory leaving the night. After tracking close to even year-to-year for late October/early November, the show then really caught fire in the last three airings. The penultimate Monday (2.3), the Monday finale (2.5) and the Tuesday finale (3.0) were all up double digits vs. the corresponding fall 2013 episodes, including a whooping +25% for the last episode. I give it just a B+ because I don't think it overachieved that much in total; after all, this was still almost 10% behind the previous spring season. But it was definitely at an A level in the closing weeks. Grade: B+.
