The TV ratings are in for Tuesday, January 17th.  Here are a few highlights:

• On ABC, Agent Carter (read Evan's review here) was down two tenths (1.3, 4.6 million viewers) at 9 p.m. from its last original episode, which scored a 1.5 in the 18-49 demographic.

• The double dose of Parks and Recreation on NBC continues to perform better than expected, staying mostly steady from last week's numbers, taking only a slight dip (1.3 and 3.47 million viewers, down from 1.4) at 8:30 p.m.

• The Flash aired one of its best episodes to date against a rerun-packed night, with "The Sound and the Fury" (read Dave's review here) at 8 p.m., but the numbers showed a series low, with a 1.3 rating, pulling 4 million viewers.

• The CW's Supernatural didn't fare much better at 9 p.m., as it was also down a tenth to 0.8, with 2.13 million viewers (tying its season low).

• Don't think that just because Supernatural has been running forever that it can't grab good ratings -- CSI proved that some old dogs have great new ratings tricks.  Moving to a special Tuesday slot, CSI leapt up to 1.6 at 10 p.m., with 10.27 million viewers, helping (along with reruns of NCIS and NCIS: New Orleans) CBS win the night overall in the key 18-49 demo.
