Ricky Gervais may have appeared on the season finale of The Office on Thursday night (he once again played original Office boss David Brent), but that doesn't mean he actually thought the show was good.

On his blog, Gervais sorta blasted the guest star-heavy episode of The Office, comparing it to a ridiculous edition of Extras that featured Chris Martin.

Watching The Office finale may remind some of the Chris Martin episode of Extras.

"It's only Warren Buffett. What are you doing in a paper merchant's in Scranton? It's mental."

If you're going to jump a shark, jump a big one.

Ouch. Gervais went on to write that he would never, ever, ever think about replacing Steve Carell on the hit show. "You don't start a company to work on reception."
