In their protective roles, angels are in no way Precious Moments-like creampuffs. Most of what one can say about angels can be flipped around and said of demons. Demons, however, have no message of their own to tell, they only have lies so they can undermine God's message. Since they don't have their natural purpose, the demons' very existence is twisted up and broken. The Devil is generally pictured as peer to the archangels such as Michael and Gabriel.
Humans tend to get freaky when an angel shows up.
We quiver in fear or fall down in awe. But angels themselves are not really that big a deal. We're more important than angels are. They are acting on Someone Else's authority, while we make our own decisions, act as distinct persons, and are responsible to discern God's ways by what God has given us. God made us , not angels, in the image of God.
