ABC comes out the gate swinging tonight with the network airing the most new episodes. From 8 to 10 p.m. ET, fans of procedural dramas have a real feast on their hands as Will Trent, High Potential, and The Rookie airing new episodes back-to-back-to-back. It's also The Rookie's Tuesday-night send-off, as the long-running series will move to Monday nights beginning next week.

As for NBC, the network airs a full night of basketball with the San Antonio Spurs vs. Houston Rockets game airing at 8 p.m. ET. It's also a ghost town over on CBS, which airs only a new episode of Harlan Coben's Final Twist and repeats of NCIS and NCIS: Origins. You have a bit more luck on FOX with a double dose of medical dramas as new episodes of Best Medicine and Doc begin at 8 p.m.

As you'll notice there's also the sneaky inclusion of a new Netflix show. If you're hungry for a reality competition series while we're currently in a drought (before American Idol begins next week), Netflix introduces its newly rebooted edition of Star Search, which premieres on Tuesday, Jan. 29 at 9 p.m. with its first of two live shows this week (the other airing tomorrow night).

So, what's worth watching tonight? The best bang for your buck, especially if you're a fan of all three shows, would be sticking it out on ABC and watching the full three-hour block of Will Trent, High Potential, and The Rookie. You can always catch up on Best Medicine and Doc on demand or on Hulu tomorrow... unless you're a One Chicago fan, then your night is already booked!
