The thing that I love about The Flash and about superhero shows, in general, is that it's not about having superpowers that makes you a superhero. You don't have to be The Flash and have super speed to do the right thing. You can be a great reporter or you can be a cop, like Joe West, and still fight for the things that matter.
I think it always makes for great television when two characters actually take time to realize that they want to be with each other. You have to leave it to the writers to know what makes great television.
