I liked it

I think it's pretty good, not great but enjoyable. It has plenty of good moments, certainly more than you see in the trailer. Saoirse Ronan and Sam Rockwell are very good as is everyone else. I think the story is clever, at least it works for me, and I'd describe it as a bit of a knowing farce. And it all looks very nice - I suspect they made good use of the 'actual' locations or something very similar.
