LOVED IT.
Loved the 'Dies Erie' for the Extremis theme. Loved the effects. Loved Loved Loved Ben Kingsley.
Only thing that got me was that the lovely Rebecca Hall has a very similar on screen presense to Gwyneth Paltrow. They sound a lot alike as well. Tiny beef though.
If it's the last we see of Downey's IRON MAN, it was a great ending.
