I think the key to sitcoms is giving yourself time to "know" the characters. Perhaps the subject of episode one wasn't the perfect way to start the series, but I think it has climbed in hilarity with each episode. There are so many witty one liners and funny segments in each episode. Emmet's mom is just a supporting role but she rarely utters a line that doesn't leave me laughing out loud. Seriously, watch this show, give it time, and you will love it!
