I have to go with AVP. The quality of the lighting, sets, general design, technology, acting, script etc etc were superior in every way to AVPR. Despite the fact that the gore and death reality level in AVP were pathetic at least it was a grand looking film. AVPR, for me was let down by a B grade cheapness which I couldn't get over, along with gore so over the top it couldn't be taken seriously. These films should be Science Fiction with a horror twist, not the other way around.
