British comedian James Corden finally debuted his US TV talk show on Monday (23 March) and, surprisingly, The Late Late Show With James Corden has received mostly positive reviews so far.

The 36-year-old opened the hour-long CBS show with cameos from Simon Cowell, Chris Rock and Eddie Redmayne, while other guest stars included Mila Kunis, Tom Hanks and Meryl Streep.

Reports had circulated for weeks that producers were worried American audiences would not "get" Corden's British humour, but Twitter reactions and reviews from critics suggest that the Into The Woods actor won them over.

The Guardian's Brian Moylan described Corden's debut as "witty, inspired and horrendously charming," while Diane Gordon at The Wrap said the premiere episode was an "impressive first outing [that] will make you smile."

The Hollywood Reporter's Tim Goodman noted that "as first nights go, this was a winner for Corden", while Michael Slezak from TV Line concluded: "Corden came off as charming and unexpectedly earnest for a late-night host."

Some viewers who enjoyed the show also flooded Twitter with complimentary tweets for the comedian, including:

However, not everyone was pleased as other viewers failed to warm to Corden's comedy:

During the episode, Jupiter Ascending actress Kunis is reported to have confirmed her marriage to Two And A Half Men star Ashton Kutcher, while Hanks dressed up as the characters from his famous movies including Forrest Gump and Apollo 13.

Clearly elated that his first night went without a hitch, Corden tweeted a few hours after the show:

Celebrity guests expected to appear in the coming weeks include David Beckham, Kevin Hart, Michael Douglas, Will Ferrell and Simon Cowell.
