The Office (UK) What happened? (spoilers)

[BottlesOf]

Ok, I'm a little late in the game, please bear with me.

So I bought the DVD of "The Office" The Complete Series, First and Second Seires, blah blah whatever.

I start watching it, and I love it. First season: hysterical. Second Season: Even better. Usually when something is as hyped up as this was for me, I'm disappointed, but this exceeded my expectations.

Until, the last 2 episodes. Then it gets all sad. David is fired, Dawn leaves and doesn't get together with Tim, everything goes wrong. I'm all depressed now. Is the series over? That's it? I'm so sad....
