How good was the Era of Good Feeling?

The Era Of Good Feeling was the period from 1816-1824 in which there was only one political party, the democratic- republicans of Monroe. This time is often questioned wether if it's good or bad. To me this period of history is actually misnamed, as there were lots of tensions going on in the United States. One being,the crisis over slavery in America was turned aside from the Missouri Compromise. The Missouri Compromise, was introduced by Henry Clay, and was passed in the year of 1820 between the pro-slavery and anti-slavery combined in huge United States Congress, involving slavery in the western territories. There was also the Monroe Doctorine, where in 1823, president Monroe, warned all the outside powers not to interfere with affairs in the Western Hemisphere. This ment that people could not travel farther west to create new colonies because the United States would not involve itself in European affairs or interfere with existing colonies in the western hemisphere.
