No surprise there. Nearly everyone was disappointed with the ending because it was rushed and way beyond the original author's imagination. I loved the overall show, but I do stand by what I said about the previous point. I've seen all seasons twice.
I'd already been "pre-warned" that when the ending came around, I'd be massively frustrated. I didn't realise the ending had arrived really to be honest, as the final season seemed shorter than the other seasons, or at least felt like it went faster, but almost immediately when I started hearing the tense music playing about 5-10 mins before the episode end I had a feeling that it was about to come...
I have to say, overall, it's one of the most unsatisfying pieces of TV I've ever experienced!

About to head off to work in 20 mins or so for a early Sunday morning (5am start!) shift today... luckily only a 8 hour shift so should be just about bearable! See you soon, Administratans!
