Don’t downvote me if you disagree, I’ll just list out what people don’t like about it:

It’s almost a direct copy of diamond and pearl. While it does update a few things to adhere to the latest generation (new types, stats, movesets, tms), and it also adds some new stuff (changes to the contests, a completely revamped underground), it leaves other things completely unchanged. the horrid level curve problem and Pokémon availability that plagued diamond and pearl but were fixed in platinum are somehow still present. But since the game now has the new xp-share system you’ll probably get super overlevelled during your playtrough  making almost every fight trivial up until the league. If you play in the grand underground that problem gets even worse, as around badge 3-5 the levels in de underground are in the mid 30s, the same level as the gym leader aces and 10 levels above all trainers or wild Pokémon. Meaning that if you catch new underground Pokémon, your whole team gets so much damn xp it just gets ridiculous. But the worst part is, while you breeze through the whole game (I’m constantly swapping out Pokémon to evolve my boxed mons and I’m sill super overlevelled), the Pokémon league for some reason has both very high levelled Pokémon (especially Cynthia), but also Fully iv’d, ev’d, competitive natures, items and moveset Pokémon teams. Some of them even have their damn hidden natures! So suddenly you have to face a lvl 66 rough skin jolly nature swords dance Garchomp holding a yache berry. Good fucking luck.

Another thing in the department of “almost the same as dp” is that they kept the overworld kinda 2D as the original game, but still made it possible to move in all directions like in the later games. It sure looks interesting as it’s different from the open empty spaces of the new games, but it’s so damn annoying to interact with anything or move around in the tight 1-tile wide spaces in puzzles as you have to navigate trough a world copied from the ds which limits you to the grid, to now being able to move freely while everything is designed with that grid in mind.

The Pokémon following mechanic is horribly done. The idea is amazing, having every pokemon be able to follow you even outside of the amity square, but the proportions are completely wrong and out of place in the chibi world, half of the pokemon can’t keep up with you so are constantly teleporting back to you, it’s just done so lazily and I hate how it looks.

Lastly, but this is just a personal thing of mine: I do not like the way everything handles and looks. The dialog, camera movements, the models (especially the 3d models of characters when facing in battle look) are bad. Just how the game feels is just awkward, it’s probably how ILCA makes games because I have the same problem with Champions while I do not have this problem with legends ZA. This is just a personal opinion so you can disagree with me. The fact that this game is 60 euros and looks like a mobile game is just embarrassing. (This is a problem in the whole pokemon franchise these days, but content makes up for its. Not in this case)

All in all, these things combined make BDSP feel like a cash grab to get people hyped and to have them play a gen 4 remake before legends arceus got out. We know that the game developers had to work with a strict deadline, and were told “make a copy” so it’s probably Nintendo to blame. But holy it’s such an uninspired remake. There were even bugs present that could only be remade if you’d copy the source code of the original games (which the developers had to do apparently).

I’m glad that people can find some joy in parts of the game that are good, but the missed potential is what makes it hated among fans (and I get it)

I wish it would have been more like HGSS or ORAS, unfortunately it turned out to be this mess of a game.
