You are just dealing with typical old school Nintendo fanboy stuff here on this point, you won't get any good responses.
I must admit I did laugh when the "it's a FIRST PERSON ADVENTURE!!!!" defense appeared - it took me back 20 years.
Not even RPGs make these excuses anymore.
Games like Elden Ring, Avowed have 10s of weapons, builds, playstyles. Each of them are fun, precise. Good hit stops, impact and sound, precise dodge etc.
Even something like Fallout 4, Starfield I can play 100 hrs just shooting things.
This year alone I played Doom TDA, Ninja Gaiden 4 with insane gameplay. Both are tighter games like Metroid.

All the ingredients are there in this to make something amazing. Morph ball can be used for parry, block, with use of bombs to destroy enemies after. Can put different beams at holding a button that can be used instantly to destroy certain parts etc.
But it does have improved gameplay mechanics, there's lots of new abilities that'll allow for new and more complex puzzles, gameplay and variety. There's a bike for faster traversal. New morph ball specific abilities and traversal mechanics. Etc. Etc.
I mean you can punch and kick in Super Mario 64. Would you really want the devs to make an entire fighting-game move-set for Mario instead of focusing on developing brilliant platforming? It's not a fighting game or even and action game. Combat and enemies are there all the time but it's not what's important to a game like that.
Am talking about defense force that dont want better gameplay.
From what I am seeing, core mechanics of aiming, encounter design etc seems to be from old titles.
If they are able to shake things up with new mechanics remains to be seen. Am waiting to play it to draw any conclusions. It does seem to have more complex level design and move set apparently from say MP3.
