The Flash (rapidly) sidesteps that idea by making emotional openness and honesty a fundamental aspect of its narrative approach.
The video highlights an arguably overused dialogue trick on The Flash, but I would contend that it is nice to see a superhero show that wears its conversational heart on its sleeve in such a way.
Sure, Barry Allen has been known to withdraw himself from those he loves now and then, but he is a real chatterbox when compared to someone like the perpetually grim Oliver Queen.
When it comes to superhero fiction (particularly on shows like Daredevil or Arrow) much of the drama comes from characters’ inability or unwillingness to open up to one another to share anything meaningful.
