You're not alone, 6sidedlie.
I don't want to make comparisons to the other seasons JUST yet, but TUF5 is holding up well compared to the rest of the seasons. If memory serves me correctly, NONE of the fights before the semi-finals were anything to brag about. It's hard to compare seasons when we're only on the fourth or fifth episode, too.
After next week, it's going to get a lot more interesting.
