I liked Gervais's stuff. The office took a bit of getting used to, as with all of his shows it's not just about him. He's helped many actors along the way. Mackenzie Crook, Martin Freeman and who can forget Dawn, the receptionist. I liked his other stuff other stuff such as Derek and Extras. again due to the supporting cast. They weren't perfect but I found them entertaining.
Gervais is probably a very irritating person to be around in real life. Frankie Boyle seems to take a pop at him, but I don't think he cares if people like him, which contrasts to most narcissistic types I've come across, who seek attention but need to be liked and can't cope with rejection.
The cringe worthy traits of his characters that are self mocking and uncomfortable obviously don't appeal to everyone. I've heard many say they like the Office for example, but can't stand Gervais's character.
How he manages to get asked to do the Golden Globes speeches baffles me, maybe the Hollywood types need bringing back down to earth from time to time.
