I can't agree. I watched an episode of this show on an airplane and thought it was horrid. The acting seemed really sub-par and the plot was a real eye-roller. Everyone has different tastes, though, so I'm not surprised that other people like it.
It's on CBS or channel 6, Monday Nights at 10/9 Central. Personally I used to love the show, but the constant drama between Leonard and Penny was just getting ridiculous.
