Here's my take on the festive special , overall I found it an enjoyable episode , better than a lot of the festive specials , loved the design of the reconnaissance dalek and the overall plot . One slight drawback for me , was the exit of Graham and Ryan , I thought they spent too much time on it and it didn't impact on me as much as say , Rose , Donna , the Ponds , Clara or Bill . One final note , if you thought The Doctor was upset at Graham and Ryan leaving , wait till you see her when Yaz gets killed at the end of the upcoming series , its gonna happen .
