Yup. If you ain't been reading batman or GL for the past few years, you'll be just as lost with issue 1 as you woulda been with issue 851.
Which kinda makes this whole thing a moot point.
If you're gonna reboot, then f**king reboot. This half ass stuff is only gonna confuse these new readers, who probably weren't gonna keep reading anyway.
I mean no offense, but, do you really think you're gonna be sticking around reading comics for the next 5 years or so? I mean, if you didn't do it before, I doubt you're gonna up and do it now.
