Mark-Paul Gosselaar has to be one of the all-time great, comedic actors of Saturday morning television. Am I going out on a limb when I say that Mark-Paul's show, "Saved By the Bell," was probably the best teen show of the 1990s? No.
A lot of what made the show was Mark-Paul's comedic talent and timing. Unfortunately, it's possible that his fame as a child/young adult actor hampered him in getting solid roles as an adult.
Yes, he had his run on NYPD Blue, but many of his other roles were less than memorable. Take for instance the show, "D.C." that aired during late 1999-early 2000 in which he played a young lobbyist on Capitol Hill. Unfortunately, that show lasted just a few shows, but I found it enjoyable.
