You and me both. I remember thinking our TV was cheap or shitty because the images never looked like this:

I went to Radio Shack a handful of times when I was 12 or so trying to buy better coaxial or component cables to “fix the problem,” not really understanding the fundamental issue.
I don’t care how it was intended to look- seeing those blocks pop in HD is so much more satisfying than muddy pixels smeared across a CRT.
