Sat down to watch the full movie through in all its glory this time. The Blu-Ray resolution and clarity is great for seeing the intricacies of his suit coming together - love those sequences. Plus we get to see the snippet at the very end with Nick Fury...
I am still truly impressed at how great the image quality of the Blu-Ray format over DVD is. For some cool comparisons check out Xylon's thread on the AVS Forum. Without trying to steal his thunder, here are two of the files from his comparison (warning they are chunky - and you cant see the diff in the thumbs :-)
