The TV series are the best. I find the things I enjoyed watching the most were TV series that you could spend a whole day watching one after another. My favourite show from Netflix's is most defiantly The Vampire Diaries ,it is literally the best show ever and if you don't think you'll get addicted you will soon be proven wrong. Other TV shows I enjoyed watching our Fresh Meat and The Inbetweeners.
The films are quite old. This is either a bonus or disaster for some. The majority of the films on Netflix are older with occasional recent flims but I have watched some really good 90's films due to the older theme.
You can cancel anytime. The best thing about Netflix is there is no contract or subscription so of you feel that for one month you won't be able to indulge in your monthly dose you can cancel it and then being it back next month.
You can watch it on your devices. I like to either watch it on the TV via my wii or my iPad. So as long as you have internet you can watch Nexflix's anywhere.
So now comes the crucial question will you be purchasing Netflix ?
