There’s plenty to check out on broadcast TV tonight, Tuesday, March 18. Take a look at everything airing throughout the three hours of primetime.

Tuesday nights are packed with new TV shows. There is some bad news for fans of a particular medical drama, as there is a season finale tonight. We’re also getting closer to the end of another season of a popular reality series.

4 shows to watch and 1 to skip tonight (March 18)

It isn’t possible to watch everything live, so we need to find shows that we need to watch live and others that we can wait until the next day. While there are three hours of primetime, it is possible to stay up and watch an extra hour or TV if you don’t need to get up for work too early. Also, if you’re in Canada, just know that Global TV currently airs FBI: International at 7 p.m. ET/PT instead of 9 p.m. due to the amount of shows to watch.

So, let’s start with the first show of the night to watch. You need to tune into Will Trent. The series has certainly focused on how Will made the right decision turning Angie in and getting out of that toxic relationship. Look, I enjoyed them together, but they’re not right for each other. However, Will is about to face more betrayal in the new case, as he looks into the mysterious disappearance of a teenage girl.

You’ll then want to tune into FOX for the next hour of the night. It’s time for the season 1 finale of Doc, and you know that you need some answers. Amy faced Richard during the previous episode, and Richard managed to get himself out of a tough situation. Sure, the evidence is stacking up against Richard, but he’s been able to turn it around on Amy and threaten to lie and get others to lie for her. He says that he was covering her mistake, so the finale is sure to set up her figuring a way to prove that it was Richard all along.

Then you’ll want to turn your attention to The Irrational. While FBI: Most Wanted is also on at the same time, it’s already been canceled, and ABC has a rerun of High Potential, to The Irrational is the logical choice to help ensure it’s renewed. This episode sees the murder of an actor, which means we’ll see Alec show off his acting and singing skills.

After all of that, it’ll be time to watch Deal or No Deal Island, so make sure you record this one. In the previous episode, David had to eliminate one contestant and pick another to face The Banker. We know Phillip went home, but this episode is a chance to find out who will play The Banker and who ends up being the second elimination. Then, of course, it’s the battle of the Final Three.

What about the show to skip? St. Denis Medical is the one to watch on catchup the next day. It’s already been renewed. This episode will see Joyce turn to Alex to be the executor of her will when she eventually dies, and Bruce gets some unexpected DNA results.
