BDSP was the worst game ever released by GameFreak.
They avoided Platinum content with the excuse of being "faithful" to Diamond and Pearl, but they've even cut DP content like Underground secret bases, Pal Park, most of the Pokémon Contest and Multi Battles.
SwSh's Zelda trees look bad? Don't worry, we're making it all chibi for you, because, you know, "faithful remakes".
People say SV was bugged. Yet this game is more faulty than SV and SwSh combined, as they literally copypasted the entire DP code from the Nintendo DS ROM while barely doing any effort around the code other than removing content of it, thus bringing the old softlocking and crashing bugs from DP and creating new ones such as UI softlocking, new duplication glitches, two savedata corruption bugs, the list goes on.
Making Cynthia the strongest trainer battle in the whole mainline games on her rematch was great in concept, but any idea of difficulty was instead boiled down into becoming the easiest game in the whole franchise due to the Affection (a.k.a. "Ashpull") mechanic being fused with Friendship, making you cheese the whole game without any effort as your Affection mary sue powers will grant you all-time miracles to keep your pokémon alive and doing critical hits.
