The Catholic Cavemen propose a list of sequels that fail to live up to the example set by the original:
Frank Sinatra, Jr.
Desi Arnaz, Jr.
Ronald Reagan, Jr.
The New Coke
The New Europe
New Jersey [my favorite on the list]
I don’t agree with the full list, especially the commenter who suggested Star Trek II! (There’s one in every crowd, I guess.) But I can tell you that Paul Joseph Smith, Jr is far superior to the original.
