"Yay" in an awkward way? Instead of flaws I would have preferred something that gave the living Gwen more story potential besides being a foil or a love interest. I feel the Spider-Man remake did great at making Gwen more than just a damsel in distress; it made her the true heroine of NY.
I really did like the Stacy twins. Sins Remembered was one of my favorite stories ever and I felt the ending to that story was beautiful. That aside, having Norman mess with Peter's girlfriend was disturbing and truly villainous. I bet it elevated him in status as antagonist.
I've already had a LONG thing about why Gewn in the movie was bad so I'm not getting into that again. If you're interested you can read about it here on my blog.
Sin's Past turned Gwen into a character for me and it served as a great reminder just how evil Norman truly is.
