I was surprised that I did not find the aspect ratios to be an issue.
They way people were talking about it, I thought the movie would switch between 16x9 and 4x3 or something. I did not expect the difference to be black borders on the right/left.
Watched on a device with overscan, the difference is invisible.
Btw, I am aware that Comcast has Army of Darkness in its free onDemand pool of movies. I don't know which cut it is, but if it's extended, it would be a digital source, if not HD.
