Great tv show from 2016. If a tv show can manage me to stay hooked on the whole tv show online, that's really impressive. I know it's know from being a mainstream popular tv show, but honestly it's a really entertaining tv show. Remember, no matter what, you have to watch Line of Duty - Season 3 online. This tv show is different, thanks to director. Praise him for it. Write in comment how much you liked it and what's your rate.
