Tom vs Adam vs Lucas

[Atticus Finch]

Really tough call for a whole host of reasons. I loved Tom because of his human side and for the fact that he came across as more "real" as opposed to the James Bond style of spy that an earlier poster describes Adam and Lucas as. He had a conscience, which was ultimately what led to his downfall as section chief. Tom could never quite justify some of teh tactics used by the secret service. He was also first section chief we saw and the group dynamic of Tom, Danny and Zoe was excellent. We got to delve into their daily, personal lives as well as seeing them at work.
I loved Adam for his action-man style, actually for his style in general (I wish the costume department would have sent me his Gucci and Belstaff gear when he'd finished with it). The family side of things was explored well and you genuinely got to care about Fiona, Wes and him as a family unit. I'd really hoped that they would spare him from death when he decided to leave (if only to spare Wes from being orphaned).
It took me a little longer to really warm to Lucas but it happened eventually (about halfway throuigh season 7). I very much enjoyed his performances and it was enjoyable to see the return of Russia and a nod to the Cold War with his introduction. I liked the fact that his character was significantly darker than Tom and Adam as well and, although I'll admit I didn't like what the writers made him in Season 9, he played it brilliantly.
Of course, there are two other section chiefs we haven't mentioned. Ros, who was fantastic and the most maverick of all of them. Loved her loads....and of course Erin, who just didn't get chance to stamp her character all over the series (by the time we were getting used to her in the role it was all over).

Anyway, a tough call and really only a hair's breadth between them but, if pushed, I go with Adam............just.
