For me, part of the fun of it is having an interconnected superhero universe on TV -- first Arrow, now The Flash, and then the hero-team spinoff that's currently being developed (though not officially ordered yet). Marvel still hasn't really given us that on the small screen yet; we've had Agents of SHIELD and Agent Carter, but they were set in different eras and each show aired while the other wasn't on. And it looks like the Netflix Marvel shows will be released one at a time and have little connection to the larger universe outside them. So getting to visit two different heroes per week in the same universe, and see them frequently interact and reference each other, is a pretty unusual experience. We've had it before with other connected shows on the same network like Buffy and Angel, or on a more occasional basis with things like the Star Trek and CSI franchises, but it's a major part of comic-book storytelling that's never really been embraced in TV adaptations of comic-book heroes until recently, and it's good to see in Flash/Arrow. Given that all the other DC shows on other networks stand apart in their own separate realities, it's nice to see this thriving shared universe evolving on The CW.
