Eh? What's 'coola boola'? By the time you're half way through season three, you'll know. If you're looking at this, then there's a strong possibility you've already seen this on TV or have had it recommended to you by someone who has. And so you probably know just how good this series is. It is, and I can say this without fear of contradiction, the best irish made TV drama series so far produced. The TV critics did slag it off a little in season one, but it's one of those shows you just have to stick with as the story builds, and the back story to the main characters also builds. By season two things have changed considerably for the gang, now under new leadership, but the central characters are still driving things along at a much faster pace now. In season three, well let's just say it gets 'complicated' for all concerned, and violent, and bloody, and some just won't survive it all! Buy this with confidence, if you stick with the 'gang', you'll be eagerly awaiting season four, bring it on.
