Yeah, I've been really enjoying it.
The daft stuff is just .. Daft. The rule about deadites needing their head cut off only to have one still be alive later just so someone can stamp on the head. And the Chase being a dust cloud that possesses people... *shrugs*
I think canonically, you can take whatever you like from it. It's pretty much on the same level as the fanfic comics you can get where he's fighting Jason Voorhees. If you mentally separate it from the films, it's easier. In this version, even though it uses clips from ED1 & 2, just assume bad shit happened in the cabin and Ash went home WITH NO CRIMINAL INVESTIGATION TO WHY HIS GIRLFRIEND DIED.
I'm not sure Lucy Lawless's character adds up either as she's, like, nearly 50... That would put her as being about 20 when her 20-odd year old mum died in ED2. >_>
