The Legend of Korra:
If you were originally a fan of the Avatar the Last Airbender series, you'll fall in love with this show in a heartbeat. You'll instantly adore every single character, even the antagonists. Although some could argue season one was rushed, it was still highly enjoyable. I, myself, am looking very forward to season 2 of this series. If you haven't watched it already, I recommend doing so now.
Law and Order:
Again, if you love cop shows and drama, Law and Order is the show for you. Every day, and when I say every day I mean it, when I come home from school I sit down and watch this show. It's captivating, breath taking, and heart racing. Sure, you can watch SVU and Criminal Intent, but nothing gets more classic than the original Law and Order. You're missing out if you haven't watched this show.
Castle:
I love this show so much it has finally turned me into a fangirl. The relationship between Castle and Beckett is something to praise. If you like cop shows, drama ,and romance, I HIGHLY recommend this show. It's definitely one of my favorites, if not my top favorite show.
