Daily Mirror reviewer Kevin O'Sullivan said watching the show was like enduring the same joke over and over again.
"Once, the beauty of the best-selling show was its remarkable ability to entertain non-petrolheads," he said. "Trouble is ... they ran out of new ideas long ago.
"Top Gear's wacky races and inane stunts have become an embarrassment."
The Guardian's Sam Wollaston likened the hosts to "uncool uncles" and said the show's stunts were "stupid, pointless, puerile and proved nothing".
Viewers also voiced their opinions, with some petrolheads backing the famed series but others expressing disdain.
"Excellent job guys. Good laughs, good guests, interesting cars, beautiful nature, crazy driving. Brilliant just keep it up," one fan wrote on the show's website.
Another viewer, David Pickles, said it was "a bit scripted/staged" and Nick Horton labelled it "boring, formulaic and tired".
Journalist and TV celebrity Piers Morgan also weighed in on the show's ratings on Twitter, and suggested Clarkson might need to start looking for alternative transport. "Top Gear beaten by Countryfile in last night's ratings? Oh dear ... #TaxiForJezza @JeremyClarkson," he said.
Another Twitter user added: "Top Gear used to be very funny. Now it's not. Stop making it BBC."
Even Clarkson himself was half-apologetic: "Thank you for all the kind comments about last night's show. It wasn't our strongest but we do have some gems later in the series."
Filming for the episode sparked controversy in Northland this year when council failed to properly consult with local iwi about the use of the land.
Ninety Mile Beach and some of the surrounding roads were also closed during filming, upsetting residents.
