There should be a name for it. That feeling you get when a new series seems to stumble after a strong pilot. The episodes exhibit some of the characteristics that initially won you over, but something isn't right...and there's at least one head-slapping, "How could they?" moment that makes you wonder if the time you invested was wasted. I'm an advocate of giving promising new shows a chance to find their feet, but episodes 2 and 3 of Glee have got me worried.
Just to be clear, I still like the show very much and it deserves to be around for at least a season since whatever Fox comes up with to replace it would almost certainly be worse. But a few points concern me:
I have no plans to stop watching Glee; it's funny, observant, and usually comes from a place of genuine sweetness. The show's mannerisms can become traps. If you've fallen for the first three episodes too, then let's all hope that the storytelling wins out over bad habits.
