I really loved this movie. Saw the first one, but not the second so was a little lost on the aliens reference. Brought my two oldest (8 &10) and wondered were they too young. It's rated PG-13 so I took a risk anyway but there was enough discretion during those awkward scenes so as not to be answering questions on the way home. Robert Downey Jr was awesome as usual in this role but normally I love Gwyneth Paltrow and was not overjoyed with her performance. She seems a little wooden actually but this is super hero stuff and she is so better at period drama. Guy Pierce has come a long way from "Neighbours" (the soap he stared in) in Australia. Great role by him. As usual leaving the story open for yet more was very typical but worth it as I think people want more Iron Man.
