I can't believe I haven't written this sooner. If you read my post on the Arrow tv show then you know I love that show. Yes, I know season three and four were not as strong as season one and two. But no, I don't think they were horrible, nor do I do as many viewers do and let "Olicity" overshadow every other story happening. From Arrow sprang the Flash. The Flash is not a spin-off but it is in the same "Universe". What this means is the shows have crossovers, characters will be on each other's programs and they will be mentioned and help the other character many times off-screen.
The Flash is a good show. It is different from Arrow in many ways. First, the Flash has superpowers. He is a speedster, this means he can move at insanely fast speeds. He can run so fast he can literally run forward or backward in time. Something he learns only creates many, many, many problems. The show is more lighthearted than Arrow. For one the hero has never been a killer. He doesn't believe in doing such things. He also has more fun in fighting crime and the people of Central City where he lives actually love having him around.
If you like the idea of watching a superhero show that is fun, and adventurous you will like the Flash. You don't have to watch Arrow to understand the Flash except when they do crossover episode but they only do these once a year.
