Well, my initial problem with Singer was that he came into this saying that he wanted the Ultimate X-Men to become more like the movie X-Men, which shouldn't be done because they are two different teams. I know that the casts are extremely similar, however, the characters are different and a lot of what has happened hasn't been brought into the UU so it's hard to do. Another thing is is that he's Wolverine heavy. Marvel has made it clear that they can no rely less on Wolverine by taking him out of the UXM for a while, however, I can sense Singer put a cloud over Wolverine's head and I've got a feeling we're going to see a lot of that. I mean, Cyclops, the leader of the X-Men, was pushed into a miniscule role in the second film, which I wasn't too happy about. Also, it seemed that he'd over look everything that the other writers had already done and do his own thing, which isn't completely bad, but to say that you're going to do that is sort of bad, since a lot of what the other writers on this title have done is leave certain things open for other writers to build on. Maybe this is why Vaughan's coming in with the five-part arc to wrap things up, however, I do feel that Singer should add to continuity, not ruin it.
His ideas may or may not be good, however, I would like to see an elaboration on Gambit. He's a character that I really like in the Ultimate Universe because, he may not be on a team, but he's actually pretty important. I'd say he'll leave Beast dead, however, stranger things have happened... The Danger Room shouldn't be too big of a deal, however, I would like to see some of the characters training or whatever. It's always cool to see characters max out and the DR is an oppurtunity to see that. Also, Proteus may not be a good character to mess around with... I thought Millar was going to do something with him, too, since he liked the character, too. We'll see, though. Maybe a Proteus return is just what this title needs. After all, that was one of my favorite arcs.
We'll see, though.
