Wolverine: No, no, don't change the subject here. Why aren't you dead?
Magneto: Oh, that. Well, you see, that wasn't me.
Wolverine: Oh really now?
Magneto: It was actually Xorn's twin brother, possessed by the sentient mold Sublime, pretending to be me, pretending to be Xorn.
Beast: That defies all logic!

"At this point, since we now have all of the possible references contradicting themselves, this neutral researcher says "to hell with it" and closes the subject."
"Hawkman can talk to birds. He also can't talk to birds. Sometimes, he can't even speak normally at all! Even if he could talk normally, or to birds, there are no birds on Thanagar, because it does not exist. Hawkman was sent here to study Earthly police methods, because Thanagar's own methods suck! That's OK though, because Thanagar still does not exist! Yet it is populated by peaceful barbarians! Who are stupid, and also warlike!
Like all non-existant Thanagarians, Hawkman has human legs! Which are reincarnated legs! Alien legs! Egyptian legs! Thanagarian legs! Bird legs! God legs! Bird-God legs! This is because he's... a God! An Earthman! A Thanagarian! An American! An Egyptian! A common human! A reincarnated prince! A hawk! A God! A God-Hawk! A Hawk-God! A God-like Hawk God of Other, Less Godly Hawks!"
"Of thereís one thing we should all know about the comics industry at this point, itís that it never lets anything go away forever. And thatís not a new trend, either. The historic 'Flash of Two Worlds' story in 1961′s Flash #123 finally reintroduced the Golden Age Flash to the regular DC Universe, establishing that he was a super-hero on an alternate dimension.
This of course led to the eventual return of the entire Justice Society in Justice League of America #21, and the idea that the super-heroes being published monthly existed on just one of several Earths in an entire multiverse of infinite possibilities...Final Crisis: Legion of Three Worlds [revealed] that three completely different Legions ó four if you count the one from their eponymous cartoon ó were all operating in different branches of the time stream at the same time, and all of them could interact with the regular DCU timeline, although the primary one featured in the comics would be the one old people liked. Because that was way simpler than parallel worlds, right?"
"This whole mess doesn't remotely fit... MOVING ON!"
"Ah, yes, Doctor Who. Because thatís the other thing 'Immortal Sins' does — play up Torchwoodís heritage as a product of Doctor Who, with explicit acknowledgment of both that show and The Sarah Jane Adventures. This is, to say the least, weird. Not least because attempting to fit Miracle Day into any sort of coherent shared universe with Doctor Who is, shall we say, a challenge... Itís also worth pointing out, because someone is going to, the massive continuity screwup that happens in the course of all this intertextuality, which is to have Jack know about the 'fixed point in time' stuff roughly eighty years before he jumps on the exterior of the TARDIS in Utopia and actually learns about it. Sure, you can work around that if you really want to, but the reality is that itís a gaffe, and one that speaks volumes about the lack of any actual oversight going on here, since itís the sort of thing that Russell T Davies would typically catch in his sleep. (He might decide to ignore it, certainly, but heíd catch it, and itís tough to see why heíd ignore it, since itís extraneous to the scene.)"
"The TV show follows Duncan MacLeod, played by Adrian Paul...Duncan isn't the same guy as Connor, it's just a rather incredible coincidence that two Scottish warriors of the same clan with the exact same background became immortal after a battle within a few decades of each other. or the most part, the TV show seems to pretend that the movies just aren't there, because there are a LOT more immortals running around in the show, and it's almost assured that Duncan lops the head off one of them an episode. The movies only feature a bare handful of immortals, so as you can imagine, the stories of Duncan and Connor aren't really supposed to mesh.
In Endgame, they mesh with all the subtlety and grace of a train derailing (a plot train, as it were). By this point, the plot holes are just incredible, and you can't even call the repair job 'retconning' because now they don't even bother explaining anything. Connor never won the Prize, there have always been a bajillion immortals, and worse, there's a continuously refreshing supply of them!"
Chris: Zod gets Clark alone so that he can talk to him in his hilarious Michael Caine-in-Batman-Begins accent, and I finally get to know what itís like when people overhear me and my friends talking about comics, because this is just hilarious nonsense. Thereís some stuff in there about how Zod has been possessed by 'the original Zod,' so now heís DOUBLE-ZOD, with twice the hate for Clark!
David: Two Zods, One Crystal.
