The low scoring complaint is so transparent. If teams were awarded ten points per goal (or whatever), it'd be mentioned far, far less.

A lot of Americans aren't into soccer. They don't grow up watching it.

This is probably why soccer isn't popular in the U.S. If it was because of the low scoring, us Americans wouldn't like baseball. However we do like baseball. We applaud pitchers for pitching perfect games and no-hitters, regardless of the score. Not to mention baseball is considered AMERICA'S PASTIME!!!
