I thought #1 was good, and half expected #2 to be a bit of a let down. Not a bit of it. Particularly if you have (or have had) a young family, you'll recognise the stresses and strains Mr Incredible goes through as he looks after his own kids, even if he has super powers. They do to, so it's the same family conflicts only up a range or two.
   The action is great fun. The plot has a slight twist in it which I confess I didn't quite see coming. It's a good film. Watch it.
