At the risk of sounding like an old man yelling at clouds passing by, I'm going to go out on a limb and make a grand sweeping statement: sitcoms today, by and large, suck.
They've become totally dishonest and care more about not pissing off their audience than they do about genuinely making them laugh. For this reason, '90s sitcoms will always have a leg up on their 2000s counterparts — it's just a fact.
