I think the big problem is that the cut the budget for season two so they are really drawing things out. Seems like this season is "stuck." Hopefully the midseason finale will move things along. Also their search for the girl is getting pretty sorry now. Also how quickly did Carl make an amazing recovery?
Yes, the search for the girl is the most ridiculous thing. I think they are just using it as an excuse to stay on the Farm though. More people need to die, more zombie heads need to be exploded.
