Let me get this straight: of all the actors on OLTL, the "actress" that portrays Starr is/was the shinning star?
No, she wasn't. She did grow up on OLTL, and as a younger character she was unique and quite interesting. But as others have mentioned, her teen years were pretty awful. I wasn't surprised that the new regime wanted to bring people over from OLTL; but I was very surprised that the first one announced was KA/Starr. She's OK, but I still don't get why they picked her over so many others.
I think Maurice Benard is just an obvious problem. With less rehearsal time and more focus than ever on big melodramatic moments with no breathing room, bad acting seems to take more prominence. I have not watched GH regularly in recent years so maybe Laura Wright is always this bad, but I don't remember her being this bad. Jen Lilley was terrible at Robin's funeral. DZ has been bad recently. Lisa Lo just seems to be phoning it in. Kristen Alderson has been terrible in the scenes where she has to rage over Cole and Hope. Kelli Sullivan is horrible.
I will gladly take the poor acting of JL, DZ, KS, and Lisa Lo over MB and SB any day, though. Those two have been terrible for years
no matter what the story required -- SB just stares and furrows his brow while MB struggles with getting more than a line or two out at a time. It's painful to watch. While it's true that many of the others have had their bad days, they have had some pretty good days, too. JL was believable with grief before the funeral meltdown, and I've enjoyed KS poking Carly with a stick and her disgust for Sonny. DZ is OK when he's not screaming or kissing Sonny's ass. Ditto for Lisa. I won't defend KA or LW, though.
Anyway, all this is to say that for me, the problems with GH start with MB/Sonny and end with SB/Jason and LW/Carly. Everything else ranges on the scale from tolerable to enjoyable.
