ELI5: Why does my N64 look so much better on an old CRT than my 20" LCD flat screen?

Also, input lag. Maybe I'm just imaging the lag, though- it's so difficult to track lag that's under a second.

It looks better because of the lack of pixels/lights in old TVs, which gave 3D objects a smoothing, fuzzy-ish effect. You could say less is more. When you play an old game on a new TV, you can see the sharpness and edges and that's why it looks funny. Also they weren't designing much for hi-def TVs since nobody really had them at the time (most computers were still big, boxy monitors.)
