Many of you are making the mistake of looking at this too superficially. Evil Dead isn't "trash," though it is a B-movie. There is a very fine line between what we call trash, cult classics, and B-movies. To address the point made above: while it is true that Evil Dead is a cult classic, suggesting it isn't trash implies that a trash movie can never be cult. I find that logic confusing.
Look, there are plenty of trash movies that have achieved cult status, such as Troll 2. A "cult" film is simply one that possesses a dedicated, obsessive fanbase. Evil Dead certainly has that, but being a cult film doesn't preclude popularity. In fact, Evil Dead is one of the most popular horror films out there, watched by people who don't even typically enjoy horror, yet it remains a cult staple because of its specific following.
Troll 2 is pure trash, yet it is a cult phenomenon. Why? Because fans hold annual festivals in honor of that movie, and there is even a documentary about it.

Time Out maintains a solid list of trash films here:

What I am attempting to convey is that if a production is labeled a B-movie, it doesn't automatically make it trash, though it certainly can be. The same applies to cult films; being cult doesn't necessitate being trash, though many cult films are indeed trashy. The distinction is subtle.
Evil Dead is a B-movie, and a great one at that. Here is the definition of a B-movie:
A B movie is any film that isn't created for an art house scene, but has a low budget. But that's not all that sets this type of movie apart, particularly when it comes to the horror genre. Most B-horror movies feature bad special effects, far-fetched storylines, and lackluster performances from their stars.
It is equally superficial to claim that "trash" is defined solely by a low budget. By that logic, Halloween would be considered trash, which it clearly isn't. Having a small budget doesn't make a film trash. On the flip side, you have high-budget trash; take James Bond, for example. By every technical rule, Bond is a trash film—it’s just been produced with a massive amount of money.
