I just watched the finale, so if you've not seen it yet, STOP READING!
Wow, loved it. Very emotional. Great scene in the underground garage. I do wonder if in a real situation, they wouldn't have been allowed to leave, but I guess Stan was in emotional turmoil. I wont lie, I shed a tear or two during the phone call to Henry. I thought we might get a bit more than just watching from a distance as Stan explained to him though. Also kind of curious as to what will happen to Paige. I guess she'll be treated like she knew nothing?
For me, this ranks right up there with some of the best TV I've seen. Great story, hardly ever any 'but why on earth did they do that? No-one would really do that' type thing, great characters, well acted, good ending.
I still think back to that episode in Season 3, when they were planting the bug in the mail bot and the old lady was still there, as being one of the most memorable episodes of TV I've seen.
