I'd say that it really depends on the person in regards to whether or not the artwork will attract or deter them from a release. An example are the
Funimation SAVE titles. If the series is great and expensive or out of print, most people will bite their tongue and go for the budget release, which always come with crappy artwork which I guess is intentional for many reasons. It's the same with the
Greatest Hits releases of games and such, which usually have a bunch of "
10/10 GAME OF THE YEAR EDITION!" logos all over them (cue the infamous image of the
Batman Arkham City boxart). It's very clear that many people aren't pleased with the way they look, but also the fact remains that many people are in it for the content (i.e. the discs themselves) and don't care if it came in a paper sleeve. I know a lot of people who throw away their slipcovers for example, whereas on the other hand I know people who pay crazy prices for Disney Slipcovers on eBay and such.
I guess it depends. In general, I'm the kind of person that would pay double just so I get a box art that looks better, because at the end of the day when I'm owning something physically, I'm buying it for the whole package. I want it to look good, and to be pleased with my purchase. I love packaging, art, typography and all of that good stuff, so it makes a difference to me. I have a weird fixation with graphic design, actually following which companies worked on certain DVD's/blu-rays and such.
Having said that, I also like a good deal so I don't mind buying a film with less then stellar art as long as its cheap, but rest assured that if it's a movie/show that I care about, I'll import and limited edition for triple or quadruple the price if I have to just to own the definitive edition, even if the disc is essentially the same. Box art in and of itself has never has gotten me to purchase a show/movie I wasn't
already interested in, as I'm usually already acquainted with a show/film before I purchase it.
Basically, I've never turned down a release due to bad artwork, but if there exists a release with better presentation/artwork/packaging, I'm going to go out of my way to get it. Memories on blu-ray comes with crappy huge Australian age rating? Still getting it, because it's Memories! But if somebody released it in a slick steelbook or the likes? Double dip!
