Are the majority of sitcoms a bunch of “one-liners” strung together with terrible acting?

Or is it just me? I do not watch TV on the TV anymore, well when they are on air for the original time. I got nostalgic the other day, and saw “Melissa & Joey” (2010– ) staring Melissa Joan Hart and Joseph Lawrence on Netflix . The nostalgia was not the actual show, but what they have done in the past such as Blossom (1990-1995) and Clarissa Explains It All (1991–1994) & Sabrina, the Teenage Witch (1996–2003).

There was a bunch of “one-liners” with not so good  acting, actually really terrible. Now, other sitcoms might not be as bad with the acting, but I thought back to others as well, and searched through Netflix, so for most of them, there was the string of “one-liners,” and the acting was average at best. The “one-liners” are blunt, and most of the time not even funny, but more for a quick reaction by the viewer.

I do understand that “Melissa & Joey” (2010– ) is on air at ABC Family, so the quality is not as high as network TV, but I have looked at sitcoms from the networks, and I find that the same type of “one-liners” strung together with the sub-par acting.
