What every console did bad(there is no perfect nintendo console)

NES-N64: Bad graphics
GB-GBA: Out of the blue in a bad way + bad graphics
GCN: The controls are weird
Wii: There is no HDMI port
DS and 3DS: Why are there two screens? I only need one.
WiiU: Too expensive
Switch: A paywall for everything
The worst issue: Switch
The fixable issue: Wii, DS, 3DS
Oh and also, there are paywalls for 3DS and onwards, so I will say DS is ultimate! It got both casuals and hardcores hooked up, it has quite a lot of good games(New Super Mario Bros DS, Super Mario 64 DS, Mario Kart DS, Mario Party DS, etc.)
Runner-ups: Wii, 3DS, WiiU

I'm like 90% sure this is bait, but I'll bite anyways.

The issue with graphics is that you really can't retroactively criticize them. Like yeah it looks like shit compared to the technology we have now, but a) that's part of the charm and b) in order to compare it fairly, you have to compare it to consoles of the era.

This is really vague, and see above.

I don't know if you mean controls or the controller. If the former, that's a game by game basis. If the latter, the Gamecube controller is probably the best thing Nintendo's ever done in terms of controllers.

Aftermarket mods always exist, but even then the Wii had some great looking games. I'll always reference the opening sequence to Planet Wisp Act 1 in Sonic Colors. Even with standard composite cables, this looks amazing even 11 years later.

Because it's a cool gimmick.

Not exactly the main issue, the issue was the crappy name as well as lack of third party support. The first party support may be kick-ass, but it's the third parties that draw the outsiders in, and if you can't get those, you're done for.

This I'll agree with at least. Nintendo's online servers were never great, being either Nintendo WFC (RIP) or Nintendo Network, and putting a paywall behind them hasn't fixed the issue. This combined with Nintendo's increasing anticonsumer practices and the worst first party support on a home console (which also throws a giant middle finger to Wii U owners like myself, being that 90% of the first party offerings are Wii U ports, as well as the best selling game on the Switch being a Wii U port), effectively killed any fanaticism I had in the company. Splatoon will always be there to tempt me back in, but they have a long ways to go.
Shoutout to the first real home console offering of Pokemon that made me swear to never give a single dollar to Game Freak or the Pokemon Company ever again. The series had been on a downward trend since X/Y anyways, and this represents the absolute nadir of the mainline Pokemon series up to this point.

About the NES, SNES, and the Game Boy family..why? Like yeah, the graphics don't look amazing now, but back in the 80's and 90's, it was revolutionary, pushing technology at the time to its limits.

I'm not entirely sure what you mean about the controls being weird on the Gamecube. If you mean the layout of the buttons, yeah, it's kinda wonky, but you get used to it pretty quick.

Like Wazz said, the screens are a cool gimmick. Mario Kart DS wouldn't be the same without the logo maker.

The Wii U is the same price as the Switch and Wii? Is the Switch overpriced then? Honestly, the biggest problem of the Wii U was the lack of third-party games.

And the Switch. Besides Free to Play games and Online, where are there paywalls? And where are there paywalls in 3DS and Wii U games? Mario Kart 8 had DLC, which is different from a paywall. Like yeah, the mobile games have them, but not the Switch. The biggest problem with the Switch is no longer lack of third-party, but the amount of crappy third-party.

Yeah. Compared to the Atari 2600, I'd say the NES looks pretty good.
