Men In Black 3 is now UHD but Men in Black 3 + Xbox exclusive Friends in Black is still only HD. Movies Anywhere seems to be mapped to the Xbox version which means the UHD version doesn't import to Microsoft. It would be
good to see this fixed.
Also, it's been about six months since this related question was asked: Any idea if we will hopefully see the awful "movie + bonus" versions (of any resolution) go away and be replaced with the much nicer movie and separate, individual extras? I
hope Microsoft is making an effort to remove this segmentation like other platforms have. There should only be a single version of a movie and it should include all relevant extras.
Not long ago a movie was on sale for $8 and I rushed to buy it. I searched for the title and accidentally bought the $20 bonus version. I had to get refunded, which included a lecture that Microsoft was generously giving me a one-time courtesy (yuck - it
should be automatic and unquestioned). I then correctly purchased the $8 version. Because it was on Movies Anywhere I was able to watch the extras on another platform, but I shouldn't need to leave Microsoft.
