I am so disappointed that the star rating of this series has been lowered purely because people were unhappy with amazon's service! yes, it was pushed back several times, and it was months after the original date that we finally received it, but that should not affect how people rate the quality of the show.
After having such a build up I was actually slightly worried the show might not deliver, but I needn't have worried.
This series has changed the formula slightly, the characters are all different, taking new directions and growing in personality. I think the fresh take on certain characters and plot lines came at exactly the right time, and shows how inventive and skilled the writers are.
As always, J.G Thirlwell has delivered a brilliant score, and I look forward to that being released (hopefully after series 5 has been finished?).
I don't want to go into the plot, or what exactly happens in this series, for one thing that would be difficult, but also I wouldn't want to ruin anything. If you are a fan of the other three series then you will definitely enjoy this, the humour is excellent, and there are a few episodes that will blow your mind!
