I tried to like Tamara and Greg (mostly because I like the actress who plays Tamara a lot), but they had such a terrible subplot, they just made me cringe everytime. So glad we got rid of them, although it was quite a bit anticlimatic:

"Oh, and by the way, you've been working for an evil force of magic all along, and this eleven-year-old boy realized it two minutes in. Look at your life. Look at your choices."
