He’s right, the game looks rough as fuck at certain times, and Nintendo definitely gets a pass more than other devs.
It's a systems driven game on 6 year old dated hardware that wasn't exactly cutting edge at the time.
Context matters.
But I guess, it'd be the same people complaining about how this game looks and how an XBOX One S game runs VS a fully kitted OCed 4090 specced out PC of the same game. Or just an XBOX One S VS a PS5. There are just clear levels of hardware differentiation.
And Nintendo has ALWAYS gotten shit on for it's graphics 'situation' for as long as I can remember. That shit really kicked on about the N64(tho I can still remember people complaining about the power of certain other consoles VS the NES and SNES), slightly eased up on GC, and then never ended from the Wii onward.
Still though, he is right, it is 'old looking' for very obvious reasons. As for 'bland', it'd be in the eye of the beholder.
But it is what it is. "IMO and given how important visuals seem to be to others". Not sure why he used this as a screen, and also not sure why he'd want the game to be dinged on graphics. God of War 2 looked great for the PS2 at the time....but it was also released the same year as Crysis and in comparison....well, you work with the hardware you got.
