Mr. Beer type brewing typically turns out like this. My bro did it once for fun with similar results. Chunky, yeasty, carbonation all over the place, etc. I gave my father and other brother one of my extract homebrews. They had a "oh no, not again!" look on their face, but after pouring it they looked completely surprised. After trying it, they said "You MADE this? It's clear, it has a head, and it tastes pretty good!".

The problem is that Mr. Beer gives very shallow and simple instructions on beer making. If you want to do it right, you have to read up.
