I agree with your philosophy of negative star ratings. I think they are truly rediculous, and I hate it when I see other critics handing out ratings like "-****." To me, it really takes away credibility.
As for the X Cup itself, this was the worst one thus far. However, I didn't fully hate it and something about TNA brings out my inner mark, so I tend to be easier on the shows. I hated the first two singles matches, but I thought the second two were decent. I enjoyed both tag matches and I thought the 8-man elimination match had a good ending. As for the tag title matches, I guess I enjoyed it more than most people did (I didn't think Dallas was too bad at all), and I would have given it an additional star.
Good review this week though!!
