I already created a thread on this, but I did it in ban appeals/reporting. So I re-created it.

My first episode was Rose, I think. It was the first episode of the ninth doctor.

My first episode was also Rose, I was like 5 or 6 years old back then. It kind of scarred me, I still get chills when I walk past a shop dummy even though it was years ago. And watching Spearhead From Space years later didn't really help either.

My first episode was Voyage of the Damned, and immediately after that, The Snowmen. Christmas 2012, channel surfing. Bet that must've been confusing, all different! 

I started with Season 1 Episode 1: An Unearthly Child, and went from there in order.

my first episode was in 2005 S2E0 The Chrismas Invasion

My first episode was also Rose and then I started watching doctor who.

My first episode was Smith and Jones, from there i watched Doctor Who in this order: season 3; 2; 1;4;5;7;6;Classic Who;8;9

i can't remember because i was only around three when i started watching it but the first one i remember watching was School Reunion (i mean that is the furthest back i remember the little me watching)

my first episode was Father's Day.  I remember watching it with my sister. it was the first episode i ever saw.

My first episode was "The Eleventh hour" when it randomly came up on the tv, I didn't even know what doctor who was.

my first doctor who episode was the first one with rose to

My first episode of Doctor Who was "Rose" when it first aired in 2005. My dad showed me it since he watched Tom Baker when he was a kid. I have been watching it ever since and have seen some of the classic episodes

My first episode was Rose, which I watched on someone's YouTube channel. They had to cut out some of the beginning and end though, for copyright reasons.

My first episode was Unearthly Child. I decided when I was checking out the series that when I was going to check out the show from the beginning, I'd go back as early as I could, lol

My first episode was technically The Impossible Astronaut (Series 6 Episode 1), because my parents were watching it with some friends and I saw the Doctor start to regenerate and ran because I was terrified. My first full episode was The Curse of the Black Spot (Series 6 Episode 3).
