The Greatest American Hero - Season 2 is excellent tv show from 1981. If a tv show can manage me to stay hooked on the whole tv show online, that's really impressive. It's probably the most known Adventure tv show and it's really entertaining. It wasn't easy to leave the cinema, when I saw it first time. I've been a big fan of such cinema for some time. You can watch it online here on and add your own subtitles if you are not native english speaker.
