Great tv series produced in 1971, from this director. Adam-12 - Season 4 is one of the best tv series creations, I've ever watched online. These days, fresh tv series coming to the cinemas, do not have 'something' what this tv series has. You just have to watch it! There are many reasons, although I would pay the greatest attention to immortal acting. Adam-12 - Season 4 is worth watching online, espacially if you can watch it for free here. Even in the most popular Hollywood tv series, there is the element of commercialism, that is elements that are in the tv series only to win favor with the mass audience. For sure, no one will remain indifferent. It is definitely great. After watching, write in comment how much you liked it and what's your rate.
