If you think about it, aren't most human dramas just about power plays and masturbation? Aaaaaaaah! just cuts the shit and, with a wink and a nod, gets right to it.
All the characters have been reduced to ape like behaviour, so they all speak in grunt instead of clear dialogue. Despite this, there is a story between all the characters and tons of social commentary to boot.
For absurdists and fans of random humour and shock, "AAAAAAAAH!" is your saving grace. As Monty Python used to put it: "And now for something completely different".
