The Marathon Merlin watch

Do you know anyone who has hardly watched Merlin, or has NEVER watched Merlin? Are they keen to watch but don't know where to start?
If so, Then continue reading!
A friend of mine came to stay quite recently and had never watched Merlin before, and I was determined that before they left, they would know the full story line through-out the whole show.
But they were only staying for 10 days.
 Merlin has 5 series', each with 13 episodes. That's 65 episodes.
There wasn't time to watch all 65 episodes, so I came up with a list of 38 episodes which spread through out the whole show and covered the full story line! We watched a few episodes a day, and completed the list just in time!

So if you are in a similar situation to mine, or if you want to watch a short Merlin Marathon, then here is the list:
