I've seen parts of <em>The Rookie</em>,<em> </em>and it's on my "to watch" list. I also have friends who are absolutely obsessed with it, too. While I can see it's clearly an engaging watch, I'm curious to understand what about the show makes it such a hit. I like Nathan Fillion as I'm a fan of <em>Firefly</em>, and I know he provides a great performance in <em>The Rookie</em>. I enjoy other procedurals, like <em>Chicago Med </em>and <em>Law & Order: Special Victims Unit</em>, but eventually, shows like these start to run out of storylines.
