"The intelligence of her dancing burns even brighter," wrote the Guardian's Judith Mackrell in a four-star review.
"The flair and virtuosity of her dancing stops you in your tracks," agreed the Standard's Sarah Frater.
The French star is appearing in 6000 Miles Away at London's Sadler's Wells.
Running until 9 July, the evening sees her perform a duet with Nicolas Le Riche, before dancing solo in a piece choreographed by Sweden's Mats Ek.
According to the Arts desk, the result proved her to be "as swift as mercury, as exact as a feather, as light as the sun and as eternal in intelligent beauty as Nefertiti".

It is widely believed that polling day will be on Friday 26 February.
RTÉ reports that ministers had predicted that Mr Kenny would announce his intention at Tuesday's cabinet and go to the country thereafter.
Mr Kenny has decided to allow the Irish parliament another sitting day in part to allow for an orderly dissolution.

Fine Gael ministers met for two hours on Monday night to sign off on their party manifesto.
The outgoing Fine Gael and Labour coalition, which had a huge majority, is set to lose a massive number of seats.

Micheál Martin's Fianna Fáil party and Gerry Adams's Sinn Féin have said the fruits of the recovery are not being evenly distributed.
The 32nd Dáil will have 158 seats, eight fewer than the previous one, and the number of constituencies has been reduced to 40 from 43.
Fianna Fáil, the party that dominated politics in the Republic of Ireland until the 2008 economic crash, has ruled out both Fine Gael and Sinn Féin as coalition partners.
