Did anyone see Festen at the Almeida?

I liked the film, so I'm tempted now it's transferred and you can actually get a ticket...

... but it features Jane Asher, and whatever you think about her cake cooking abilities, she simply can't act.

I've seen her in at least four very different shows over the years and it's not a case of her showing a 'gamut of emotions... from A to B' - she doesn't even leave A!

Exactly why producers hire her for anything other than the catering is beyond me.
