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

Island Living: Was a disappointment. No resorts, and the mermaids seem to be an afterthought. The conservation career wasn't my cup of tea, as it resembles too much of real life. I play to escape reality, not to be reminded of it.

Strangerville or Realm of Magic: It's a tie. Strangerville had that linear storyline and doesn't include multiple choices/endings. Realm of Magic's Spellcasters didn't measure up to the witches from TS3 Supernatural. Recycled spells/potions, lack of curses to cast on other Sims, and it's also too easy to level up in magic. I had to use the Become a Sorcerer mod just to make things more interesting, to be honest...
