This would have been better if they didn't include CGI/VFX robot arms and white liquid. It would have made the movie more realistic and more fun to watch. With the ridiculous robot arms it was just distracting because they were just poorly done and made the whole thing seem silly instead of funny.
The characters also didn't even react much to freaking CLONES in front of them at the beginning of the movie. How can you just dismiss that and continue partying? I know some of them were stoned, but not all of them. They just giggled and continued talking like nothing fantastic happened. I know it's supposed to be a horror-comedy movie, but they should have put a bit more effort to make it less ridiculous.
