Sorry, but I find this more insulting then when the rumors came out that they talked about making Johnny Storm black (and I am an African-American)...and if I was a woman, I would find this insulting too.
Okay, I've didn't get involved with the Original Sin story arch other than the fact that the Watcher got murdered. Now I find out Cap is old and Angela from the Image Universe (or Spawn Universe) is in the Marvel Universe, which sounds kind of awesome, but now she's going to be Thor's sister?! Not sure how I feel about that, does that mean they erase the fact that she's an angel? She still is an angel right? And if she still is an angel doesn't that leave on lot of questions to be asked about true divine power? Would she not report to "The One Above All"? How did she get sent to the Spawn Universe? And in the Spawn or Image Universe wasn't she a human before she became an angel? And if she was originally and always was an angel, how the heck could she be Thor's sister unless Odin or Gaea made it with an angel? A million and one questions that need to be answered. It could be very interesting if done right. Crossing my fingers that it is done right.
