Oliver Hirschbiegel's latest film "Diana," has not been met by many positive reviews from British critics.

Following its London premiere on Thursday, Britain's media lit into the movie, calling it a "cheap and cheerless" effort, according to the Mirror.

The Sunday Times said that the script was downright "embarrassing."

"Even when these lines are delivered by the fragrant Naomi Watts, doing her level best with a squirmingly embarrassing script, this film is still atrocious and intrusive," the reviewer at the Sunday Times wrote.

Yikes. But to give the actress her due credit, it seems the resounding opinion across the pond is Watts delivered a "brilliant, passionate and believable performance" playing the difficult role of Princess Diana while simultaneously having to deal with a stilted script.

The romantic drama stars Naomi Watts as the beloved Princess of Wales, and tells the story of Princess Diana's love affair with Dr. Hasnat Khan.

But critics seemed unsettled by the picture the movie painted about the People's Princess and her lover-the royal is made out to be a "sad-sack singleton," as the Mirror wrote.

There were some fans of the movie, including one critic at London's Evening Standard.

"If you do as the director asks, and check your baggage in before watching it-ignore the rows over authenticity and some inaccuracies-and see it for what it is, you will not be disappointed."
