Jack the ripper was horrifying.
Anyway as the above stated, i could not glean any instance of plot from the trailer. The highlight would be the carshots, and they were certainly pretty impressive initially, but they got a bit old after awhile. You've gotta convey some form of plot in your trailer - at least tell us what its about. Another thing of course are the massive anachronisms. Definitely doesn't look like 80s stuff. Also i'd recommend against the sudden color shifts in the trailer - tends to give an amatuerish undertone to the trailer. This trailer has the potential to be pretty impressive, but you need to get rid of quite a few car shots, and convey more of the story through the trailer.
