Savini's remake better have a better ending
For me, the biggest draw for a remake of Nightmare City would be to see how they tackle its ending. The ending to Nightmare City is probably the most contentious part of the whole experience. Some like it, many hate it. I'm in the latter category. So, I hope they don't just copy the original's ending, that they come up with something better.
Of course, the title is still Nightmare City. So, how can the film end other than being a nightmare? I just hope they don't take the title to be literal. That they mean a metaphorical nightmare in a city.
