I must have made that vow at least three times. When I found out that the sixth season (I'm refusing to call it 'series' like we're meant to here in Britain) was on its way, I thought to myself 'now is the time'.
But, I then did nothing.
After episode one - of season six - aired a little over a week ago, I once again came across newspaper articles about the series.
It was time to see what all the fuss is about.
From Monday 22nd March right through to yesterday evening, I binged through - at my own pace - every single episode to date of the crime series.
Anybody who knows me and my binge habits would know it would have taken me a lot longer to catch up to speed on the series if I wasn't gripped.
Unlike some series', where there are dud seasons mixed in with great ones, I haven't really felt there have been duds in Line of Duty. In fact, the previous season was one of the best as it had one of my favourite British actors - Stephen Graham - playing such an intriguing character.
So - I am now in the boat with the people who have been following along weekly.
And I can now see those post-episode news articles and know what they're going on about.
