Heroes was a superhero show before all the Marvel and DC shows took over. While it's not as good as the shows we get now (at least most of them that is), it was still a solid series...especially the first 2 seasons. After that the quality went down drastically but was still watchable. It was about ordinary people all over the world discovering they developed super powers. There are a bunch of separate stories that all come together to prevent a catastrophic future. The show was really popular when it first came out, so much so they tried to bring it back years after it went off the air with Heroes: Reborn. Do yourself a favor and avoid the reboot at all costs because it was awful. This original Heroes though is absolutely watchable.
