Precocious Children are Annoying

Henny, I know exactly what you're talking about. Kids who are articulate or witty way, way beyond their years are a TV pet peeve of mine.

However, I don't think "Better off Ted" does too badly on this score. Ted's kid Rose doesn't have too much to do or say, and I don't find myself irked by her character the way I am by kids on many other sitcoms.

Aww! Yeah -- I loved that they seem to have made an effort to bring Rose back into the majority of the episodes for some screen time. I really enjoy the Ted/Rose moments. I wonder if your attitude toward "precocious" children has more to do with your upbringing than anything else? The word choice alone seems to reveal that fact to a degree. I grew up one of these overzealous, over-talkative, overly-inquisitive kids. I was a pain square in the a$$ of my parents and teachers constantly asking why, and how and giving my 2 cents. Anyway, my point is that it's not unrealistic, it seems to come down more to whether or not you can appreciate that sort of trait... apparently you are more a graduate of the Milford Academy: http://www.imdb.com/title/tt0367279/ :-D

I haven't seen the entire series but I don't find her particularly precocious/advanced. She's just a normal kid with the black and white right/wrong view they have, which she was taught. And that I assume is the whole point, to show how the corporate behaviour seems crazy to somebody with a bit of common sense, even a kid. If she were precocious it would defeat the point because I think part of it is that she's just a kid realising it's crazy/immoral/whatever, not a super advanced one.

I know what you mean about kids in TV/film in general but this character is definitely not one of the worst offenders.

On rewatch I agree with this, but I think it was moreso in the early episodes. Later on they wrote her as more of a regular kid. There are definitely a couple of lines in the beginning of the first season that a kid that age would never say - she came off as a sarcastic teenager, and it didn't fit.
