What's the worst expansion pack and game pack and why?

The GP that annoys me the most is Parenthood. I get tired of the messes and the phases, and you can't discipline the children for their misbehavior during their phases. Discipline overall annoys me because the choice of discipline style doesn't seem to affect anything but some text in the relationship panel. While I like the character values, it's irritating that the cumulative affect of behavior and discipline over time affects the sims as young adults, but child and teen behavior does not reflect where the sim is on any given value at that time. And it's much harder to get a sim's character values in the red than it should be. But I do like a lot of the new interactions, and the character value system overall gives me more goals during the child and teen stages. So I wouldn't get rid of it but it does drive me crazy sometimes.

For EP, probably Cats and Dogs. I know it's more realistic, but not being able to train cats like you can dogs means that there's a lot less to do with a cat. I feel like so many resources were spent on the veterinarian career that the experience of just being a pet owner feels a bit lacking. I miss pet jobs, and I miss being able to encourage your pets to be bad as well as good. Pet CAS is great and I'll be trying out the vet career soon, but the basic reason I bought the pack was just to own pets, and they aren't as much fun as I wish they were.

I don't have DU or RoM yet, so they weren't in consideration for my votes.
