Yeah, a show consisting of drunk sex addict with money, whiny brother total contrast, and a stupid fat kid for the poop jokes. That's one of the worst shows ever created, Sheen is not the TV-GOAT, it's a crappy, "wohoo, sex joke, what's next, ohhh a drunk telling another sex joke" one joke show without actual character depth, too boring for slapstick in your face comedy, and Sheen is just another fucked up celebrity who got a hype show, he contributed nothing to the show, the brother sold the stories, the emotions, Sheen was just hanging around doing shit he does (or would if he could) in real life. Screw the douchebag and have a nice day
Sitcoms are NOT meant to have much character development. Hell look at Seinfeld, none of the characters developed anything at all during 9 years. Not saying TAAHM is anywhere near Seinfeld, but character development should honestly not even be considered when it comes to comedies.
Even Arrested Development, a so called 'smart-comedy', never even attempts to develop any of the characters. Hell by season 2 they were already re-using all the jokes/ and most of the situations/ they used in season 1
