Meg Griffin is one of the most important characters on Family Guy and was played by two different actors throughout the TV show's run. Meg is Lois and Peter Griffin's teenage daughter who has a tough time and doesn't always feel accepted by her family. She also desperately wants to be popular. Although she is a crucial part of the TV series, she isn't a universally popular character. While Brian Griffin is one of the best animals on an animated sitcom, some viewers have critiqued Meg since the start.
