If you surf the net on a regular basis, you've probably seen this article. Entitled top ten lamest avengers, moon knight is number ten, disagree but whatever. Scroll down to the comment section most of the comments are defending moon knight, good to see.

Moon Knight actually works pretty well as a solo character, but whoever gave this man an Avengers ID card should be shot.

EDIT: I just added my two cents to the comments section :P

Yea, I was about to say that this guy doesn't know much about Moon Knight based on what he said about him, and when I read the comments it seems that's what everyone else had to say too lol
