"Family Guy" is one of the best and most interesting adult comedies. Every character is truly interesting and has their own unique quirks. Peter is just a terrible person. Lois is secretly dark and covers it with a her friendly exterior. Meg is unbearably mediocre. Chris is painfully dumb. Brian fakes sophistication and intelligence. And Stewie, Stewie is the best character in the entire show for a variety of reasons.

1. His keen ability to sense the need for a musical break.

Stewie, as demented as he is, has a keen sense for breaking into song and choreographed dance. These songs are always pertinent and make the show that much more interesting.

2. His offhand references to composers and Broadway shows.

There is nothing better than an offhand reference to Gershwin. His keen ability to incorporate a musical and all its key numbers into an episode makes the show that much more exciting, and the parodies of musical numbers are always spot on and so enjoyable to listen to.

3. His ability to call his family out for their crap.

There is no member of the Griffin family who could escape criticism and Stewie is the perfect medium to deliver those criticisms. Chris is dumb. Meg is boring. Brian is pretentious. And Lois a hypocrite. Frequently, as an audience member you feel inclined to make these feelings known and no one could voice that - except Stewie. This is his function as a character and it makes the show that much more interesting and funny.

4. His intolerance toward all of Peter's annoying idiosyncrasies.

There is no other character that can tell Peter what a terrible person he is. It is this ability that makes Stewie so helpful and his offhand bashing of Peter makes Peter's stupidity almost palatable.

5. His continual quest for world domination.

Stewie's character has these interesting intense subplots that make the show really wonderful and make Stewie's character have that much more depth and sophistication.

6. His oddities.

Be it his interest in crossdressing juxtaposed with his odd interactions with women Stewie's character has funny little quirks that make him interesting and make his role in the show that much more important.

Stewie is by far the most interesting and complex character on Family Guy and he makes the show so much more interesting and fun to watch.
