"The depth of this latest series is fantastic. However, what happened to the attention to detail? There were at least three different types of plane in one flight."

Jamie, Cheshire

"Over half way through the series now, and there still seems to be more questions than answers. It was nice to see Jo and Malcolm away from their desks, as they were finally given a chance to show their full potential as spooks. It was also good to see Adam and Ros humanised as they made a mistake, and ended up killing the wrong person. No mentions of either Zaf or Ruth, but in such a fast-paced and packed episode it can almost be forgiven."

Charlotte, Chelmsford

"This episode was a fantastic roller-coaster ride on a plane which was potentially out of control. Ros' character is brilliant. Although she's been a naughty girl passing information I would beg the producers not to write her out. Hermione plays the character fantastically. Ros is gritty, no-nonsense and funny all rolled into one. She has got to emerge as one of the best characters out of the whole series. However, I wouldn't want her attending on any flight I was on!"

Debs, Sheffield

"A superbly tense and atmospheric episode. Incredibly real, good to see the team fail for once. Fantastic acting and CGI."

Matthew Judge, Newcastle

"Spooks has since its original series been one of few programmes worth watching on television. The last episode however left me feeling disappointed. It's still exciting and gripping but the script-writers need to be weary of creating something that's beyond belief."
