I also don't think the Sterling Gates issues were lackluster...they were really good in my opinion. This is good too! It's just a little different take on Banshee, they are playing up her sympathetic side.
Part of me wishes DC would just do a Superman book that doesn't have any kind of constraints on it, they just let the talent tell the Superman stories they want to tell. Perez could do a three issue arc, then maybe Ordway would get a chance or Abnett and Lanning or Hickman would do a story or two....just let the talent mix it up with the character. It wouldn't be that much different from doing "imaginary stories" like they did so much in the sixties and a little in the seventies.
I have enjoyed this book the most out of the four Super books.
