[spoilers] what is the best series of spooks

[BAUER24]

I have to sgree that series 7 was a brilliant series because of the introduction of Lucas ( who I think a lot of people will agree will be greatly missed.) I just wish that there could have been more episodes with both Adam and Lucas in. This is because I feel that the chemistry between these two was excellent, and that the more they worked together the more that it could have grown and that it would have been even more dramatic when Adam died. Also it might have been interesting to see a love triangle develop between Adam, Ros and Lucas.
