We have always been completely TV free. My dd will be 5 years old this week. She is in preschool (actually full-time daycare), not kindergarten yet. In spite of my vigorous attempts to avoid all commercial characters, she knows who Dora, SpongeBob, Stawberry Shortcake, Elmo, Princesses (Ariel, Cinderella, Beauty and the Beast), Spiderman, you name it, are. (She can recognize their pictures.) She talks about them all the time (especially Dora and the various Disney Princesses, to my great despair. Granted, she doesn't know a lot of the excruciating details about them, but really, there is not a lot of in depth conversation about these characters going on in the daycare.
So no, she is not out of things at all, nor considered weird, at least not at age 5. I don't know whether that will change once elementary school begins, but I will stay TV free even then regardless.
