Movie sequels do not necessarily have the same intended result as the original, that is, to be as good or better than the first. Furthermore, in this day and age where prequels and spin-offs are released now, more than ever, they too can be bunched into the “sequel” category since they are released after the original - but many times those disappoint as well.
On the other side of the coin, Star Wars Episode V: The Empire Strikes Back, The Godfather Part II, and even Terminator 2: Judgement Day, are popular sequels that almost outdo the original.
In sports, fans and media often compare players and/or dynasties from different eras, debating which ranks higher all-time.
