Yes, I don't mean 'marvellous' as in 'fantastically profound, artistically unparalled and the best thing I've seen all year (oh, hang on a minute...)'. More 'marvellously fun and entertaining'.

One problem may be that because it covers three books all with essentially the same plot, aspects of it were becoming repetitive by the third. I felt they handled this well by giving us the thread of the spy-glasses and eye-windows as an unresolved mystery to pull us onwards, but even so that could only take us so far.

I rather hope they don't try to make a sequel covering further books in the series, as, although I haven't read them, it looks like they must pretty much continue as before, and I think that really would be over-egging the pudding in the form of another film. As it is, it was neat, cute and rather delightful.
