I think the idea of retconning x men 3 and origins is dumb, and I hate the concept of reboots in general (the exception to the rule being nolans batman, but just cuz one franchise did it doesn't mean everyone needs to). And I dont say that simply because I'm a fan of xmtls and xmow... I'd say the same thing about terminator too. I hate t3 and t salvation (at least in comparison to t1 and t2) but I certainly wouldn't want something to come along to strike them from the continuity. Whether I like it or not, those movies are part of the continuity. If I remember correctly, that was even one of the problems I had with Sarah Conner chronicles, is that it seemed to retcon things from t3. As a personal preference I dont watch any of the movies beyond t2, but that doesn't change the fact that those other films are continuity. Purposefully ignoring certain aspects of continuity is simply put bad storytelling, and if you dont want to follow the continuity that's been established then maybe you shouldn't be making a film in an already established film series. This is my biggest concern with fc, the seeming errors of continuity this film presents (as well as bastardizing the entire "1st class" by neglecting to include the actual first class with Cyclops and bringing in jean. But in the end, i suppose i can accept beast, banshee and havok)
Luckily tho it doesn't seem like they are blatantly saying xtls or xmow didn't happen, the contradictions in continuity are gonna be rather minor and over lookable (Moira for one... Perhaps she just aged well in x3, not enough of an error to be considered a retcon. Same with Emma frost. I dont even think she's called Emma in xmow. Not a retcon. The worst is really xaviers ability to walk in xmow and x3 and still being buddy buddy with magneto in x3. A continuity error to be sure, but hardly a MAJOR plot point.)
There's not enough in this film to constitute it being a retcon or a reboot. There are some definite errors of continuity, but it should still exist well within the universe. Same with the wolverine. Making a stand alone story that doesn't reference xmow isn't the same as throwing out continuity. Unless it re explores his origin, it can still exist in the continuity simply as a stand alone story that isn't connected to the larger overall story. Which considering its a spinoff, is fine by me. And wolverine fans certainly deserve to see his story told without xmen interference. I saw xmow more of an x men prequel that happened to focus on logans weapon x roots than an actual wolverine film. The wolverine can be that wolverine film.
I'll still have my concerns about fc, due to the continuity and their creative choices, but it appears to be a good film, and it appears that its gonna exist well in the continuity (I think exploring beasts past with the xmen that was referenced in x3 is proof enough that x3 isn't being tossed out of continuity. His look isn't different enough... Plus a time difference of about 40 years can easily explain the difference in appearance)
