Sorry, I just don't by the paramedic retcon
Okay, I can buy the idea that Michael would be smart enough to pull a switcharoo with with a paramedic and escape into the night, but the way it was executed in H20, there's just no way that could possibly have been a regular person. Who -other than Michael Myers- could possibly survive being launched headfirst out of a vehicle, being rammed head on at top speed, and being toppled down a hill and crushed up against a tree by a huge van? If that were a paramedic, he would have been dead, or at least writhing in severe agony. This guy was just slightly dazed by the whole experience.... because it was Michael.
Also, don't get me started on the whole mask thing. We see in the opening flashback that it wasn't stapled onto his head or anything. The guy could have very easily removed the mask, and why wouldn't he when he was obviously being confused for someone else? Because it wasn't a paramedic in H20; it was Michael.
True, it could possibly work in theory, but with the way it all played out in H20, there is no way that was not Michael. imho.
