By no means do I dislike the theatrical quality of these laugh trackless sitcoms. Are there a lot of them? Sure. I don't think adding canned chuckles would improve them. The pauses are an essential part of humor, and fake guffaws are essentially lull destruction. My beef is with the ones that still use it (or a live audience) and don't know how to use it properly. A painfully bad series will just go for the cheap laughs and one liners, some straight from the 90's. Not that there aren't ones that use those right. Say what you will about Big Bang, at least Chuck Lorre still knows how those sort of things work. Then there's How I Met Your Mother where the laugh track is so not intrusive (is there such a word as trusive?), I kept forgetting it even had one every week. The Millers, sadly pulled because it was hurting Scorpion's ratings, also managed to handle laughter right.
But then we have the New Odd Couple and the McCarthy's and stuff like that where it's obvious joke over clever writing and the laughtrack/audience pretty much punctuate how freaking awful the show is.
