I'm a Star Wars fan that prefers quantity over quality. I think the mindset stems from the vast array of interesting, from performance to visual, characters.
Granted they're different genres, but I'll use the Dark Knight as an example. Hot Toys made Batman in both costumes, most of the Joker's looks, Two-Face and Harvey Dent. While it would be nice to see a Bruce Wayne and Gordon in there, even if they made Fox, Alfred, and a Joker Goon or two, that's pretty much it, the majority of collectors aren't going to care about background cop #2 from scene #5.
With Star Wars, some of most background or short screen time characters become very popular because of their design alone. I became a Darth Maul fan from less than 1 minute worth of footage in a trailer and a Star Wars insider magazine cover. The design alone won me as a fan of him.
I like the Pietts and the Plo Koons and types of characters that I'm sure a number of fans could live without. I think they look interesting and it's part of why I love Star Wars, it's a visually rich universe with some really cool designs.
General Grievous was turned into a cowardly wimp in ROTS compared to the first Clone Wars series, but I still got the 1:1 bust and want a 1:6 figure because I really like the character design.
That's why I always speak up again Hot Toys solely taking over Star Wars 1/6, between their prices and their "line" style, you'd never see the background, meaningless characters from them. Some people would be happy with just the core guys done really well, but I think Sideshow's done them well enough and we get all these extra guys to have a more visually rich and diverse collection, should we want it. There was a time I'd have thought a 1/6 Jabba a dream that would never happen, not only did we get him and the throne, but we've gotten a number of the critters from his palace, an ever growing collection of characters, the wall space with Han's carbonite slab, eventually the Max Rebo band. I think the Jabba setup from Sideshow is one of the best things to come from them having the license.
