Watched it earlier today, but keep in mind I have very bad day (some intestinal sensations, ugh...).
So, first thing - very nice trailers (what was the voice?), especially the second one, and opening grindhouse footage as well. As for the look - sometimes I felt that some of the print damage looks a little too soft compared to the actual footage (and some of the overlays felt like being on quite a short loop), but it didn't really diminish the experience.
Even if it was shorter (and different - some deleted footage incorporated) I've felt somehow that is as long as original, but it may be because subjective reasons mentioned earlier. Also, it looks like (and I was expeting that) you were going for more accurate grindhouse feel than I usually do. So, all the music from 60-70s etc. That's not a bad thing at all, but I feel that using more variety of music helps to highlight some scenes a little. Here, sometimes I felt that there is a similar feel most of the time which was a little bit tiring sometimes. On the other hand, the music worked well most of the time, sometimes even great. Also, I'd put some more music into the ending, because there was quite a long period of time with no music at all if I remember correctly.
I've also felt, that the music used fits Blade Runner and the mood of the movie a little too much. Almost like something that could be there originally, that is an advantage (because, well, it works) and disadvantage at the same time, because when the change of tone isn't that big, the experience doesn't feel so much different than watching the original. Some nice touches here and there make me laugh (or at least smile, as laughing isn't too good idea for me today), like some of the dialogue from long-nosed JF Sebastian's little friend, or Pris acrobatics.
Overall, very nice, stylish version of the all time classic, which I've really enjoyed, with some nice ideas included, but maybe just a little to close to the original movie's feel. I had some plans for BR grindhouse too, but after watching it, I think I'll shelve them for some time cause there's no need to forcing the open door.
