Just seen it for the first time.
I don't think it's menacing at all. As someone who lives with a DH and a DS things got quite bumpy during the teen years, but overall it's a positive message that you will get through it - although it does give the very misleading impression that your teen DS ever listens to anything you say...
I guess it's a reaction from the complaints last year that there were no males in the JL ad at all.
