Hello guyzzzzz, The Flash as you might already know is a charactor from DC universe. Ofcourse he is nothing but a speedster, a guy that can run fast.The fantastic thing about this series is itsa adaptations from different theories of Einsten. If you are a person who knows about the parallel universe and astro-physics, then dive in.The series by now has completed 4 seasons with 24 episodes each. You can say 4 of which may be just filters. But still the story line in good.The first appearence of the main hero, the flash was in a different series known as ARROW as Barry Allen. But back then he was just a human. A detective who is highly skilled but was always late for work.The story begins with an experiment on dark matter going out of controll and the dark matter gets infused with the humans witin its area of contact, giving them special abilities.Later on the hero forms a team-( actually the team found him) and the story goes on with fiction, romance, heartbreaks, theories , friendships, sacrifices etc.Every season ends with a thread to next season. The space-time relations and the existance of parallel universes are depicted in this series.I can talk about this the whole day. Better watch it for yourselves.
