I have watched all the episodes except for the last one - I set to record it but my VCR ate my tape (although thanks to the internet I am all caught up). At this point, though, he has eliminated everyone that I liked. Of the ones left, I really don't care who wins. My opinion is that with this season they put so many new twists into the mix that this is much more about the competition and less about anyone finding love. At this point he has left the loudmouth, the slut, the overly agressive one and unless last episode she did something that really stood out, one that I hardly knew was there. I am not all that excited to see how it ends.
I do find it kind of funny to see how they keep pulling Charlie's brother into the show for no particular reason.
