It might be that you missed the point. The acting was fantastic, just not something you personally enjoyed. The plot was put together really well and doesn't harm the original, if anything it makes the relationship between Deckard and Rachel more important and builds on the world fantastically well. It might not have been to your tastes and that is fine, but many of us found it extraordinary and are still falling for that movie with every subsequent viewing. The audience I saw it with gave it a standing ovation and that is a rare happening in a movie theater. If you are too uptight to just accept it wasn't for you then fair enough but it was not a crap movie.
