Firefly was a masterpiece from start to finish, it could have been even better if given the chance to flourish. There's no way that this series can't take the top spot. It's literally got everything you want in a series.-
Buffy is a childhood classic for so many of us, but whether you watched it as a kid or as an adult you can't deny the story will stay with you forever and the re-watch value of this series is off the charts.-
One of the newest series in this list: Grimm. It was great throughout every second, the character development was crazily good and I was pleased to see the show ended on a high note rather than overstaying it's welcome.-
Person of Interest is perhaps one of the most engaging and addicting shows I've seen in a long time, I was drawn in from the very first episode and remained that way right up until the end.-
Friends... Do I even need to say more? I don't know of a single person who doesn't know this series and it's such a loveable show that has so much re-watch value that it's unreal. I've personally re-watched it multiple times.-
True Blood was a great series for not just romanticising vampires as a majority of vampire films/tv series seems to do lately. The twists and turns always keep you on your feet and the character depth is truly something else.-
Fun, witty, and action packed. White Collar will have you falling in love with criminals, or maybe even wanting to be them. It's a great series with wonderful, loveable characters that you'll be rooting for throughout.-
Parks and Rec is such a perfectly relatable and witty show that it deserves a place in this list just as much as the rest. The comedy is top notch, the characters are fantastic and it's perhaps one of the most addicting series to watch.-
House was a series I grew up with during my teens, the characters jump around so often it leaves you a little off balanced but all in all it's a fantastic show and well worth a watch, especially if you love sarcastic humour.-
Angel may not quite live up to it's predecessor 'Buffy' but it's still fantastic none the less, with loveable character, sparkling wit and wonderful storylines it's a show that deserves it's place in this list just as much.-
