I don't have one particular episode that stands out, but I have several. I believe I've watched ASiP, ASiB, HoB and TEH more than any of the others, because those are my all-time favorite episodes.

The Reichenbach Fall (for obvious reasons)

And His Last Vow because there are such brilliant and strong scenes acting-wise. Alone that scene in Baker Street when Sherlock,John and Mary return from Leinster Gardens is so brilliantly played it deserves all awards in the world.

 

Series One: I watched an episode a night.
Series Two: I watched one every day off( I work in school, get lots of hols) and if hubby was away.
Series Three: I watch an episode every day hubby is away with work. But I always end with His Last Vow. So if he's only away one night, that's the episode I watch. Up to date, the most recent episode has always been my fave. But even it wasn't, it would still be the most relevant.
I've only watched the Pilot twice, I think.

Yes I think HLV has the best cliffhanger...can't wait to see how it pans out!

I am so regimented in my routine...the decision is made for me!

Haha, great summaries.. I´m the same, only without the Johnlock-y background.

The only episodes I watched more than two times are the relatively painless - ASiP, SiB and HoB.  (TBB wasn´t especially painful either, but also not overly interesting..) Those three I watched maybe around.. four?.. times. I´m not someone who can see the same movie or read the same book over and over again.. (and also I have an excellent memory. )

When I was watching episodes every day, I started ticking sheets.
I've watched them all more than a hundred times. Isn't that scary.
The one I have chosen most is TRF. Maybe I just like suffering.

Study in Pink has been the most watched - it's my other half's favourite episode and we watch all Sherlock Holmes eps and films together unless I'm taking "Sherlock"  screencaps for some reason.
