My vote is also for ridiculous.
While I'm not from the US, and don't consider Thanksgiving to be as important as some do (which is why I didn't choose the "holidays are sacred" option), there is no reason to keep adding shopping hours. The stores will be open on Black Friday at ungodly hours, and so many are already open 24/7 for so much of the Christmas season - just take a deep breath, realize that the shoppers will be there in the morning, and enjoy the time off.
I see a parallel to Sunday shopping, which was introduced in my area about 15-20 years ago. Most retailers found that, once the dust settled, they were making the same amount in sales that they had before the start of Sunday shopping, but now they had to heat, light, and staff the store for one more day. I really don't see any advantage to beginning Black Friday on Thursday.
