Victory isn't that bad. Its bad reputation was mostly because Tomino was depressed when he made it and he hated it as a result. RNG was more a show targeted towards kids, so adults not liking the huge tonal difference from the previous gundam shows is not really its mistake.
CG, especially its second half was as hated as DiTF and GC was back when it aired. It was responsible for one of the largest broken base in anime community as a whole. Now you don't see that divide because most of the haters moved on to better hobbies while the only ones left are nostalgiafagging oldfags who remember the show to be better than it originally was.(Give enough time and you will see shows like SAO and DiTF regarded as timeless classics once zoomers become the majority in the fanbase just like how it happened to CG). VVV and GC isn't any different, really. Their writing was always that bad, literally bhojpuri movie level writing(but with better VAs, animation and music, thats all), CG was mostly an accident that they never expected to actually has mass normalfag appeal, only plus side would be that it had a better ending than VVV and GC. KLK wasn't that bad, as a show by itself it did exactly what it was supposed to do, that is entertain the viewers and I haven't seen much hatred for it other than in some threads of /a/. DiTF was riddled with production problems, it was destined to fail from the start. It was actually supposed to air around last season, but got pulled back two seasons ahead when not even half the script was finished and the trigger/gainax team left as a whole after episode 15 and A1 gave the project to a subsidiary studio to handle afterwards.
