Bitch, it had better.
All of which are good points; while the Rebirth analogy might not be perfect, don't you think it's more likely that Krakoa beers off course without Hickman?
Also, it's a little silly that Hickman was brought on for a specific purpose only to do such a good job that TPTB decide to stall, causing Hickman to bow out. That's not a good sign to me.
Does it need doing?
Yes.
Then it will be done.
I thought Metal was an okay idea executed just fine, but yeah, things haven't been good since and overall it seems that isn't gonna change soon. How the X-Men shake out will largely depend on how far Marvel moves away from Hickman's original plans and whether or not they refocus on characterization.
Does it need doing?
Yes.
Then it will be done.
I do love that this era has been all about building up and adding to the mythos, new concepts, new set-pieces, new characters, and not tearing it down and making it smaller and meaner and uglier (through terrible ideas like the Decimation). Growth is good, cutting back sends the wrong message, to horribly misquote both The Secret of My Success and Wall Street.
It's not the same thing. Rebirth was a complete reboot of the dc universe while simultaneously trying to have their cake and eat it too.
Hox/Pox was just a new X-men story, the last 60+ years of X-men history is still canon.
