A film starring a talking bear has scored the best critical rating ever recorded on Rotten Tomatoes.

Paddington 2 currently has a 100 per cent rating on the review aggregate site.

The film is the follow-up to the 2014 original which was based on Michael Bond's childrens' books, and is yet to get a bad review.

With 164 positive reviews, it replaces Toy Story 2's 163 reviews to take out the No. 1 spot.

The film's director, Paul King, called his Paddington films "a real labour of love".

"So many people pour their hearts and souls into them for months or even years, hand-crafting every last frame, and we are all incredibly grateful for the overwhelmingly positive response we've had so far," he said.

Critics have been unanimous in their praise for Paddington 2, with Wall Street Journal critic Joe Morgenstern calling it "The Godfather Part II of Peruvian bear movies ... a sequel that surpasses the superb original".

"It's an exquisite reminder of the wondrous things that can happen when a storyteller of boundless imagination avails himself of some rigorous discipline," wrote Justin Chang from the Los Angeles Times.

And the New York Post's Johnny Oleksinski called it "a perfect flick for families, but also a jolly time for anyone with a pulse".
