I've heard someone else mention this point once, to which I couldn't disagree. However, it's not particularly realism that these characters are meant to be reflecting, but more about caricaturing of real life.
However annoying/ rude/ ignorant/ obnoxious (et al) a lead character is in any comedy (and many of them are : Basil Fawlty, Captain Mainwaring etc ), for it to be really liked by the public, the character needs to have a spin on it. This enables the character to possess perhaps, a warmer, weaker side, but without losing that cutting edge to the part of the character that we love to hate, thus enabling us to empathise/ sympathise, whilst still disliking who they portray.
Nonetheless, Tate's capturing of the 'Lauren' character is very accurate and true to life (i.e very annoying young dysfunctional child), but there's very little caracturing or warming side to her character. It's because of that, that I find it damn right unfunny and very, very annoying, because that's how I view the real 'Laurens' in this world too, unfunny and annoying.
Just an opinion like, but not explained very clearly, I might add.
