Just finished the entire show. I am not into series that much (I couldnt do the season 1 of Breaking Bad for instance), I guess I expect a lot from a serie but the Office didnt disappoint and I can say it is a great show!!
You feel close and connected to the characters, curious about their lives, choices and decisions, you see them evolving and there are twists you didnt expect.
Yes, some seasons are weaker than others but overall it does worth watching it until the end.
So do you feel shy to jump into a 9 seasons serie?! Do not hesitate, the Office is emotional, hilarious, nostalgic, funny... in a way, that is all the ingredients of life :)
