I didn't care for BBT, either, but pretty much all laugh-track sitcoms sound like that when you remove the canned laughter. Friends, for example, fares no better. The whole pacing of the show is designed around the laugh track.
So are the jokes. The laugh track clues you in to laugh, so they don't have to work really hard to make the script work. They basically hook an audience with a few characters they engage with and some stock lines, and then just repeat the formula. Once they've got them, people really feel strongly about the characters; it acts more like a soap opera than a comedy.
Eventually, people realize that they're hearing the same few jokes over and over, and check out. But a show can last a surprisingly long time on its own momentum plus the occasional shark-jumping (adding in new elements to the story line).
Not my thing; I find I prefer single-camera sitcoms, which are shot more like movies and tend to be more comedy-drama than pure sitcom, and they usually lack a laugh track. But I guess it's all up to people's tastes.
