So I added a new couple, Andrew and Justin. I don't think this will drastically change the results of the countdown since they are probably not unpopular enough to have already been voted out.

how Mike and Catherine are worse than Danielle and Matthew???

For me it's because the relationship between them turned Katherine into a total psycho. I used to like her and I do now, but at that time she just annoyed the hell out of me. And I don't think it was fair of Mike to be with her when he clearly was still in love with Susan.
