Well I didn't want to post an spoilers, but wasn't sure if it was meant to be a send up, or it was meant to be serious.
And I dont really know Mischa Barton but thought she wasn't at all convincing. But then maybe it was the script.
But should add I fell asleep towards the end, so maybe the conclusion was so well done I would be able to forgive its earlier nonsense!
I was looking forward to it as enjoyable "nonsense", lots of nice scenery and costumes. So wasn't sure if was just me getting old and grumpy.
Poor Agatha, I think she would be quite pained by it. :)
