For those of us who are extremely disenchanted by the Friends we have seen the last two seasons, I think I know why we keep hanging on, hoping for a better tomorrow (or next Thursday, as the case may be). Every night, there are Friends' episodes from past seasons aired in syndication. We can still see Chandler's rapier wit before his character went on permament vacation (I guess he never returned from Yemen). We can still see Ross when he was a sympathetic character (as opposed to being a raving lunatic half the time). We can still see Monica when she was healthy both mentally and physically (she actually frightens me now, I'm talking nightmares). We can still see Rachel, when she had at least some redeeming qualities besides her looks. We can still see Joey and Phoebe when they were...well, I guess these two really haven't changed that much (are they too stupid for character growth or what?).
The point is, even though I have come to not enjoy the new episodes anymore, I keep watching because every night I am reminded just how good this show used to be, and perhaps could be again.
