Worst Expansion Pack?

The pets are whatever. I find I rarely add them to a family as there are too many issues. Can't go on walks properly, can't scold for poor behaviour properly, the family thinks they need to buy more pet supplies despite the fact the pet has been dead forever, all the pets in the neighbourhood are constantly sick. I could have done without this pack. I love Seasons though. I couldn't imagine playing without the change in weather. It adds so much to the game.
