Late to the party.
Something about the relaxing, nostalgic nature of the series, the lovable characters (apart from the main 2 ones big shout out to Russell and Terry) , the beautiful and peaceful scenery, the majestic OST, combined with some subtle but deep meaning scenes and the fact its dead funny* at times makes me want more and more.
I love it so much and from what it seems there won't be another series
* Christ, I was in stitches when Andy tries to give Becky back the photo with the kiss and the latter's reaction.
