I'm aware that sharing this is on this sub is preaching to the choir, but I think the discourse around this game is obnoxious and factually, provably incorrect.
For some obvious ones, people complaining about the controls either haven't played Prime 1 Remastered or haven't spent the 10 seconds needed to dig around in the settings and adjust stick / motion controls and their sensitivity. I heard this complaint come up a lot in reviews when it's fairly easy to circumvent. Mackenzie only yaps when you first enter and exit areas of Sol Valley and when you first meet him, but goes radio silent for a majority of the time exploring. It's odd you can't disable the hint system like in the other 3 games, but nothing I lost sleep over. Backtracking and linear progression is present in every Metroid game, not just this one.
For the less clear, but are equally if not more important ones, let's first talk about Sol Valley. Sol Valley is not an open world map. It does not take 15 minutes to travel across. It is not littered with pointless collectables. Sol Valley takes, at most, 3 minutes to travel from Ice Belt to Flare Pool without boosting assuming you don't tackle any other objectives along the way. (Which you should be doing) There are missiles, ammo, weapon, and health upgrades all throughout, all of which make the game immensely easier. Sol Valley is not much more invasive than Hyrule Field or the Great Sea were from the Zelda Series. Having a QoL feature locked behind an amiibo is immensely shitty, don't get me wrong, but that sounds more like a Nintendo issue than a Retro Studios issue.
The Green Crystal farm is also overblown as long as you're paying attention when the game tells you about them. I'm aware that I'm an anomaly that finished the game in 10 hours with 100% Items/Logbook, but the game explicitly tells you when you first deposit Green Crystals that you should pick them up and periodically deposit them off at the Altar. Mackenzie also reminds you to do this periodically between keys and revisits. Even when I knew that power bombs were necessary to break open the geodes, I was able to gather 3/4ths of the required crystals before the mines, where you get a radar to pick up the remaining amount. The hunt for the Crystals and mech parts are the endgame fetch quest from Prime 1-3 again in a different coat of paint.
Finally, the story being told mostly through logbook entries, implied characterizations for a mute protagonist, and connections to older games is also the same as the older Prime titles. I've seen a lot of complaints online saying that Samus acts too stoically or the dialogue is awkward when she doesn't respond. She's been characterized throughout the entire series with exception to one scene in Dread and that one game everyone hates as being virtually mute. Her body language is her dialogue, and in this game, during Flare Pool's escape scene, Samus sends the other Fed troops out from an escape pod before herself, she shakes her head and runs back to help Armstrong, and in the final sequence if you wait during teleportation scene, you can see her hand shake before activating the teleporter, showing that she has a lot of reservation leaving the rest of the Feds behind to return to her galaxy. That isn't to say there aren't things worth criticizing like the fake-out deaths (Vue having 3 is absurd) and yet another Chosen One myth being slapped onto Samus for a dying hyper-advanced space race, but people saying the story as a whole is poorly written (or at worst, character assassination) while in the same breath talking about how great Prime 1-3's story are, feel like they only digested the game's story through a video essay or wiki page.
I'm not sure how many overlapping fans there are reading this that are also Silent Hill fans, but similar discourse erupted last year during the release period of the SH2 Remake where many people were viciously mocking the game's pre-release footage and presentation, saying the game was dead on release, and making odd and unfounded arguments about the Remake's gameplay in comparison to the original SH2, and how it was pandering to a "modern/woke" audience. If it's a serious opinion and not just obvious engagement bait that someone thinks Prime 4 is an insult to the Metroid brand and the Prime Series, they need to have a genuine reassessment on why they enjoyed the Prime / Metroid games in the first place. It's a very easy recommendation for me to make to anyone that like Prime 1 Remastered to play Prime 4, and I'm not sure why some people have the opinion that this game is miles worse than Other M or Federation Force.
/rant, thank you for reading this far. You should play Ghost Song, it's a great Metroidvania that doesn't get a lot of attention. Recommend your underrated Metroidvanias in the comments plz.
