I still haven't watched the interview because the host really does seem to be very unpleasant, but YouTube showed me a clip from it where Bruce talks about how AvED failed because fans were pirating it. I know he talked about that when the show got cancelled and he was kind of (understandably) frustrated by it, while now he states it just as a matter of fact. But I'm not sure whether he's really right about that.
Everything gets pirated. The only question is if you're popular enough to overcome it. And I think that Evil Dead suffers from the same blessing/curse that Bruce's career does. That it's too well known to be called a niche or a cult franchise, but not well known enough to be called mainstream.
You could argue that Evil Dead is over all more well known than lets say the Chucky franchise, even though the Chucky franchise has 7 movies (+ the Mark Hamill remake) and a TV show that also ran for three seasons, which is pretty close to Evil Dead. But the difference here is that you can do Chucky movies and episodes much more cheaply than you could do Evil Dead. Yes, the first movie was made on a micro budget, but you can't really squeeze a full TV show from 5 people stuck in a cabin. And the one thing that AvED really deserves credit for is that they never cheapend out. They really tried to make it epic and slick and worthy of the Sam Riami brand (at least visually). So I think the problem with AvED (aside from all the other problems we may have had with the show) was that it punched too much above its own weight. It would have worked fine if they were making a show on a budget of the Chucky show, because the Evil Dead fandom is arguably larger then Chucky's, but because it's Evil Dead, the budget had to be much higher. And it got stuck in that limbo of not famous enough of a franchise to really carry the budget. And at that point, the pirating might have been just the straw that broke the camel's back.
It's I think also why they made it half Evil Dead and half a throwback early 2000s boner comedies, to I guess get another viewership group into the mix, but we've already spent hundreds of posts talking about how that turned out.
