Gloria Reuben returns to ER?

I just read on tvguide.com that former ER star Gloria Reuben will return to the show for an appearance this season! If this is true I have both joy and concern. The joy is w/ out hesitance. I have missed my favorites for some time. I cannot begin to stress just how much I loved the show upon it's original premiere a ways back in the 1990's I adored every character to the fullest, and Jeanie Boulet was one of my absolute favs. next to Mark and Carol. My heart flutters with delight at the very thought of seeing Boulet once more, for she left on an odd note, many many seasons back. The concern,however, may very well outdo the joy in some areas. The show is nothing like it once was, and I for one have seen it rot over the past season to the lowest point yet, and I don't want to see one of my all time favorite landmark characters taking part on the uselessness of what the series has become these days. The show is still quite good, but I have to admitt that I'm always let down by each passing episode except when it involves Abby. Being the longest running character know, she is the most grounded, and the only interesting character these days. The most recent episode showed Morris to actually have some depth, and total seriousness in him. Well wow! Why haven't we seen this much before. It's quite late in the game for him, but I suppose better late than never. Pratt's a pretty good ting in the show now. He's the longest running next to Abby, having jopined at the tail end of the tragic 8th season. I remember dispising his character once. He's actually much improved now, and carries his own rather well. Still, one other question remains, are ANY of these characters worthy to work alongside the all wonderful Jeanie Boulet...except Abby that is? I have to ask. I hope I'm not the only one here. It's not just Boulet, it's the same thing I would ask were the returning guests to be Clooney and Margulies as well. I was a fan of the originalshow...so to speak. With time, this show has certainly slowed down, and has not been what it once was for quite some time.
Still, this news of Jeanie Boulet is such a gass that I find myself awaiting more from it...and soon, oh so soon!Cheers!
