Yes I would. I would watch it INSTEAD of the WWE because WCW has always been my favorite and nothing can duplicate the 'thing' that made me watch it. And that 'thing' is exactly what is missing today.
No it's not Goldberg.

If Goldberg would be in the WWE, things would still not be like they were before. That spark is gone. I wish that what happened to WCW would never have taken place. We'll never see it back again, not even.. if Goldberg would sign with the WWE.
Invasion went wrong.. DDP got screwed up.. Booker T took it bad.. nWo got screwed up..
No single wrestler can change an entire company around. Not Hogan, not Bischoff, not Steiner, not Goldberg.
