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

I bought island living full price. Was running out of gameplay options in an hour. I like the mermaids, but other then that..there’s just nothing else I’m very fond of. I thought the world was pretty when I got it but now I just think it’s bland.

I only have the vampire and RoM gamepack, both I like. I don’t have it myself, but spa day sounds very uninteresting.
