This is, instead, reported to be the work print of the film that was screened to test audiences. This print was not well received, and the feedback from it is what lead to massive reshoots on the film.
I don’t think it’s fair to just this “re-imagining” of Halloween based on this print, and if you’re a fan of the series, I don’t recommend downloading it (beyond the obvious fact that it’s illegal – it’s also not the theatrical version of the film).
No doubt, though, if this film does poorly, piracy will be blamed – regardless of the actual effect this had on the film.
