Nah, I was mostly irked when one of the characters in Lookism was shown to have a 3 y/o that acted and was drawn basically half her age. By age 3 kids are running chatterboxes, not barely waddling babies who only know "papa" and "mama". I'm not even getting into how "highschoolers" look and act there - I've seen Jojo, I'm immune to ultra buff 8 feet tall "17 year olds".
As for the dad in Let's Play - I can accept that since it's played mostly for comedy and only when it comes to his family. Like I don't question, how he manages to run a business or his mental state.
