The season boasts a man Barry Allen, who is stuck by lightning and wakes up to see his heart pumping faster than the others, his whole body responds in a similar way, and he becomes the fastest man alive. The whole series features concepts of light, speed, relativity and time travel, which for a physics lover are great.
As with great speed comes great responsibilities too. He has to catch other meta-humans like him to maintain peace in the world. The season 1 was really full of suspence and made me going in, while the season 2 is a bit off the block and has a lot bad physics concepts and feels streched out too. Overall Season 1 is a must watch.
