Seriously! Calm down everyone. It's not inappropriate, and REALLY there are NO swears at all. To tell the truth, I enjoy this show. It's funny, and kinda cute. Violence and cursing aren't issues, and my little 8 yr old bro isn't throwing tantrums like Fred. Honestly, I think parents of kids over 9 are WAY too overprotective if they find Fred inappropriate.
There is only occasional flirting, no bad language, and I would pick Fred over iCarly, which is now completely "romance oriented". And of course it's annoying. It's a kid's show. If you want a kid's show that isn't "annoying", then one DOESN'T exist.
Fred doesn't have a moral. But you should expect that. After the age of eight, all kids groan when a moral is put in. A moral in a TV show is, as a nine-yr-old might put it, "ruins it". If you don't wrap a moral into it, it's not the end of the world for this age group.
I watch Fred with my little sibling and it brings us together(which not many things can do) and gives us something to talk about. It's also funny.
