That's the coward's way out, SM, I have listened to your arguments and even though I see ways to fix it, I am willing to listen to you. However, I am pointing out a VERY fatal flaw in your stance; if you launch these attacks against A:CM and remove it from canon, then these same arguments will have bearing on Alien 3 and any other films with similar inconsistencies.
This is how laws and statutes are made all over the world; you can't just put one law to apply to a specific situation, it needs to apply to ALL situations. We all have our personal canons, but if they are based SOLELY on what we want as opposed to what is in front of us, then it's nothing more than our own personal fantasies. This standard that you have set up to combat A:CM will inevitably combat Alien 3 as well unless you find a way to differentiate the two so that the standard you have set is set specifically at your target rather than all-encompassing.
