I really enjoyed I nostri fantasmi.
Sure, it's a bit corny in places, but all the roles are well played and there's some good layering of characters with the nosey neighbour variously annoying and yet also protecting the protagonists.
The film was particularly successful in making me feel sympathy for. Riondino who plays the father. Hiding in the loft of a house and watching/scaring the residents is extreme voyeurism (almost stalking to be honest) but the relatively light hearted nature of the plot meant this aspect of his behaviour was never dwelt on.
I enjoyed the film and thought it was well put together.
