Is Seasons worth the money?

I'd say so. With almost each pack I'd play for a little while, and then get frustrated and bored and quit playing for months. After the My First Pet debacle (which I didn't buy, and have no plans to) I was feeling like maybe it was time for me to quit the franchise for good. Since Seasons came out, I've been playing every weekend. If it wasn't for my job I'd play more often. The pack is really well done.
