This show is PERFECT, but this might just be my personal opinion. I remember when the show aired. I was nine at the time, "Suite Life of Zack and Cody" had already ended, and I had grown tired of odd cartoons and the under-cover pop star. Selena Gomez's show, "Wizards of Waverly Place" was the only show I was into. Then this show cam along, and suddenly the Disney channel not only has my full attention, but my (then) seven year old sister as well.
To make a long story short, I was very upset when this show came to the end. It was the only good show Disney had left.
EDUCATIONAL VALUE: There isn't really much educational things for your child to learn in this show. I personally think they will learn a lot more educational things from "Good Luck Charlie" than watching some bratty teens on a dance show.
POSITIVE MESSAGES: There are actually some pretty good morals in this show, especially in the first season, though most of them are over looked by jokes. For example, Teddy has to get a job instead of being given a phone, P.J. drops out of university and goes to a cooking school to fulfill his dreams, and Gabe learns that having younger siblings isn't too bad. These are just the ones that came to mind, but I know there are some other little morals that pop up from time to time.
POSITIVE ROLE MODELS: Can I just start off by: OH MY GOSH, all these characters are perfect, but may not be the ideal role models. They are suppose to be a realistic, funny, family.
Teddy, the teenage daughter, is a pretty decent role model. Yes, she is a typical teenage girl; she lies to her parents in some episodes and is obsessed with boys. HOWEVER, out of all the kids, Teddy is very intelligent. In several episodes she is seen studying, and there is even one episode just about her freaking about her History final.
P.J., the oldest son isn't smart, but has a good heart. Gabe, the middle child, is a prankster and often talks back, but when you have a 11-14 year old boy, just think about it...Charlie isn't a role model, but such a cutie pie.
SEXUAL CONTENT: Parents need to know that in the first season the oldest siblings sure in high school (a sophomore and a junior I believe) so, yes, flirting does happen in this show. In the first season, the (then) eleven year old doesn't know what to do about his first crush and is instantly helped by his sister. By season 4, that elven year old boy is almost fifteen so even he has a girl friend. In general flirting isn't to excessive. There are some under cover sexual jokes that even I didn't get until I turned twelve.
ACTORS: Yeah, this isn't a category. I just want to inform you all that the kids on the show can genuinely act, unlike those bratty dancers and singers. The actors have undeniable chemistry. I look back how young Charlie was at the start, but now...WOW. She has grown.
Over all, this show is great. If you are iffy with your young child hearing some sexual jokes then I recommend this show for nine years olds and up.
