That's not just something that happens in cartoons. I'm finding a lot of movies, particularly horror movies, to rely on overly stylish camera techniques. Y'know, where almost every horror movie is shot with a blue lense filter and everybody looks like Smurfs? What ever happened to good old normal color, like what we see in real life? It's sickening when everybody tries to make an arthouse flick just because.
Yeah, one thing about cartoon style, cartoons aren't taken as serious as they once were. Where as some used to have realistic looking characters(G.I Joe), love for that has dropped considerably to favor more wacky and outlandish styles. I wouldn't say it's bad they tried something new, but it's bad that they totally shun the realistically porportioned cartoon characters of the 80s. That style died around the mid 90s with cartoons like Exosquad. I think, in a way, the trend shifted when cartoons started to get more campy. Now you have more cartoons that stress fart jokes and talk about poop and armpit hairs.
