I'm not much of a Smash fan but I think a lot of that comes from the unprecedented hype cycle for specifically the Wii U version of this game leading to not only the worst feeling big budget fighting game I've ever played (except maybe Virtua Fighter but that shit was revolutionary), but the worst community too. I'll give credit that some of the new characters had inventive movesets for the series. However, just about everything about this game compares negatively to both Brawl and Ultimate. Horrendous game feel, lack of single player content aside from the bare minimum, weakest remix selection in the franchise, that awful plastic-y look, the worst character balance ever with Bayonetta... I could go on for ages about how much I hate this game and everything it did.
