It's probably a leftover from 70's sitcoms, like Taxi, where the cast would actually be adored to that extent, especially Andy Kaufman, the problem is that producers think we still get excited by Joey entering a room that we all cheer, like it's the best thing to happen to us that day.
They need told!.
I have to agree with Jeku on the irritation point, I get that too, there's just some TV I can't watch - like Mad About You, I'd happily torch the studio where they make that. Especially, when that git starts repeating his name, Buckman, like it's the best sounding name in the world - I want to hurt him, after forcing him to slap his wife.
Malcolm in the Middle rocks, can't believe I did'nt mention that, one of the best shows ever. It's a shame Malcolm is like 25 now, kinda like what happend to Fred Savage, where one summer he was fine, the next it looked like he had aged 10 years. It's funny how Malcolm is so different from every other show like it - most of the humour is cruel, but the characters are so well written that they get away with it, you just kinda feel sorry for Duey a lot
