The addition of Emma Frost really emphasizes that not only is this not the traditional X-Men, but also gives an added sense of intrigue as you know that Emma's motives are not as pure as she lets on. And the voice acting for her character was terrific, as she sounded exactly like I imagined her in the comics--an educated, sexy, but very snobbish, british schoolmarm who feels totally in control of any situation, even if she really isn't. And at the same time, there is a sincereity in her voice when she talks about teaching so she isn't completely manipulative. And the scene with Cyclops using his love for Jean and the promise he could find her as a means of keeping her around was terrific, especially knowing she plays with his effections, not to mention has a relationship with him, in the comics. The only weird thing was that Logan seemed to know more about her than the other X-Men. If she was running a rival school like Xavier's, then why wouldn't folks like Beast or Cyclops also know about her?
Likewise, Magneto and the voice acting for him was equally terrific. Obviously, the series was more inspired by Ian McKellain's take on the character in the movies, but hey, it's a good reference point to draw from. Also, it was an inspired touch that his entire fortress on Genosha is capable of being manipulated by him because of it's metal structure and incorporated it into his battle with the X-Men (although, as cool as it was when he used the metal slabs to block Cyclops's eye beams, wouldn't have Cyclops been able to punch through that? And after all, Magnero can generate an electomagnetic field around himself that shields him from that sort of attack.)
Speaking of Scott, it's still weird seeing him taking a back seat to Wolverine's leadership. Although, it might have been touched on when the X-Men got the telepathic message from Xavier in the future, there still needed to be an emphasis that this was a guy who once lead the X-Men and that being second bananna really has to get to him. Course the only reason he's sticking around is because of the hope they'll find Jean, but still.
Also, it's always a treat to see a "Days of Future Past" scenario play out in X-Men. What was interesting about this one, though, was that, unlike other apocalyptic futures involving the X-Men, Xavier is still alive in the future while all the other X-Men are dead. That's certainly an interesting angle. Also, anyone notice that Rogue's name was also among the graves? Ahh, so even though she joined the Brotherhood and framed the X-Men, she still regarded as part of the family.
There were a couple of things that weren't all that great, such as Bobby and Kitty playing the typical bickering teenage couple, and Forge acting like the stereotypical tech-savvy geek you see far too often in action movies, but there also were a couple of nice touches, such as the erea around Bobby frosting up whenever he went into "Iceman" mode, and the reactions Warren, Bobby, and even Cyclops had when they saw Emma. She knows exactly what's on their mind, indeed.
