G3 managed to start off somewhat decently, but it felt like its quality went downhill starting with it adding extreme focus to the Core 7. It felt like something that was in early G3 was missing later on, but I can’t think of what.
EDIT: I think it may likely be the series getting flanderized in some way. Not sure if flanderization actually happened, but I’m thinking about it.
The first I’ve ever tried watching anything of G1 proper was when I tried watching the G1 My Little Pony: The Movie (because it was packed in with the DVD I bought containing the G4 movie). It was so boring, that I never bothered trying the rest of the generation afterward.
