I've been wanting to get this for over two years since it was my favorite movie of 2011, but it never seemed to go on sale until just recently, then Beast Buy never had it in stock until the other day when I was able to pick it up.
My original review is here and on second viewing it still holds up, though I was able to notice the use of color timing and camera techniques a bit more. A check online of the comparisons between the theatrical PG-13 cut and this "unrated"* cut are minor; mostly trims to sex and violence that don't seem too extreme in their unbowdlerized form. It's not profound, but it's immensely entertaining and Bradley Cooper kills it in the lead. It's also amusing to realize that he and Robert De Niro would team up in a couple of years and earn Oscar nominations for Silver Linings Playbook.
The Blu-ray looks and sounds great, but it's really thin on the extras side with a pair of fluffy short EPKs - the most techy thing mentioned is the film stocks used for different phases - that add up to about 15 minutes and an alternate ending that's remarkably not as good as what made it into theaters. (Reshoots can help!) I haven't listened to the commentary track yet.
Score: 9/10. Buy it.
* The dirty little secret of the "unrated" label is that it's meant to imply more sex and violence in a movie cut - which in the case of horror or action movies that studio demand a profit-enhancing PG-13 instead of an R-rating lives up to its implied meaning - all it really means is that the MPAA didn't rate it. If Pixar wanted to insert a few more shots of sunsets into Finding Nemo and put it out as the "Unrated Edition", they could even though there'd be nothing risque about it.
