Many of the sketches in the first few episodes of Extras were like instant replays of The Office, set in different surroundings. I could not quite make up my mind wether I was disappointed or just needed to get used to it. It was like when The Office first started: at a certain point, I got hooked.
The episode with Les Dennis could be that point in Extras. It was quite amazing and both Dennis and Gervais were excellent in it, showing new sides of themselves. This looks promising.
