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

Island Living and cats and dogs is a close second. I had to go with island living because I think the gameplay was on the level of a stuff pack.

Strangerville was the game pack I did not care for. All of the gameplay revolves around one story that literally has no replay value.

The funniest part of this is I think Sulani and Strangerville are the most prettiest worlds but gameplay is everything for me in the sims 4.
