Re: New Mutants
I don't think there's anything more to be said about Wolverine in the movies so they might as well ditch that solo series and incorporate him into the team films.
Origins never really improved upon the backstory scenes we saw in X2, and there's such feeble anticipation for The Wolverine at the moment that there's a sense that little more can be done with fleshing out the character. Fleshing out some of the OTHER characters wouldn't go amiss, to be frank.
I'm pretty sure that audiences and film fans feel the same way. Imagine if Iron Man kept on dominating the screen at the expense of everyone else. We've had four movies with Wolverine at the forefront and we're about to get a fifth. Excitement for Avengers 2 has been focused largely on new characters (Quicksilver and Scarlet Witch) rather on saying 'we're going to give you yet more backstory and emotion on Tony Stark.' We know everything about Tony Stark now, his story was wrapped up in IM3.
