FLATLINE to me is single handedly the best episode of Doctor Who to date! I have loved every episode of series 8...but vosh i have seen it 6 times already and cannot get enough...a true classic <3 I loved the entire cast and the script...everything...so many iconic moments in 45 minutes....beautifully made...just perfect...and a genuinely scary threat with The Boneless.

Listen
Mummy on The Orient Express
Deep Breath
The Caretaker
Into The Dalek
Kill The Moon
Time Heist

^^ are genuine classics from series 8!

Eleventh Hour
The Doctors Wife
The girl Who Waited
A good Man goes to War/Lets Kill Hitler
Impossible Astronaut/Day Of The Moon
Vincent & The Doctor

The Pandorica Opens/The Big Bang - IMO (and until this week) my favourite finale the show has done...PERFECT intimate character evelopment but so epic in scale and a bold defining ballsy cliffhanger! nothinv can top that shock!

Time Of Angels/Flesh & Stone
Asylum Of The Daleks
Angels Take Manhattan
The SNowmen
Christmas Carol
The god Complex
The Crimson Horror
Hide
Name Of The Doctor

Day of The Doctor - a genuine tour de force pure and simple hats and Fezzes off to The Moff!

Rose
Dalek
The Empty Child/Doctor Dances
Bad Wolf/Perting of the Ways
girl In The Fireplace
Impossible Planet/Satan Pit
Family of Blood/Human Nature
Blink
Utopia
Silence In The Library/Forest of the Dead
Midnight
Turn Left
Stolen Earth/Journeys End

just to name a few there! I know it is mainly Moff era heavy but vosh i re-fell in love with the show thanks to that mad Scotsman...and truthfully series 8 has had the storngest run of episodes!

best ever Who was The War Games.

despite 10 episodes the story just keeps steadily going, withouf flagging or sagging, towards the climax.

several different plots, all interesting, woven together very cleverly

most important ever story since it introduces the time lords (had been known for some time that the dr is not human)

minimal special effects. since its all plot and atmosphere. as good drama should be. in particular, the insides of the renegade tardises are little more than plasterboard and bubblewrap !

superb acting all round. pat troughtons last story and by this time he had the dr "well nailed". and philip madoc in his best sinister psychpath mode .......

a natural climax and tuurning point in dr who as it was the end of his 6 years wandering around aimlessly without knowing tardis destination ......... dr who then changed not least because colour production meant alien landscapes wd be less convincing in a tiny tv studio ......

Sure the most important story ever is "An Unearthly Child" as it introduces the Doctor (and the Tardis).

Classic:

My favourite classic who story has got to be The Daleks. A superbly written, atmospheric and dark story. I always wonder what everyone felt on the original airing when the came face to face with everyones favourite pepperpots.

New:

My favourite Nu Who story has got to be The Time of the Doctor. A fantastic finale to Matt Smith, as well as an appropriate introduction to Peter Capaldi. The regeneration was a masterpiece. While I considered the 50th Anniversary special to be amazing, somehow Moffat managed to outdo it.

Although neither of these two are my outright favourite whoniverse stories.
