No, we need more characer developement. That was what ruined X3 because of the hack director who somehow found his way into a franchise with opputiornity and descided to destroy.
More character developement or bust
More character development my ass.... For what? If either director did his job early on in the movie, there would be no need to develop them any further after the first film. If that's the case, why not make the movie a drama with no special effects at all.. And they can run around in their tight little leather costumes complaining about how the world hates them, without doing anything about it, but flying around in their expensive jet, and living at a techno-savy secluded mansion.
No claws or attitude for Wolvierine, no telekenisis for Jean, no lazer beams from Scott, no absorption from Rogue, no magnetism from Eric, no metallic mayhem from Piotr, and no warm and fuzzy Hank... Is that what you want, for sake of getting to "know" each character?.... You must be out of your #<$^% mind.
If the director gave the most popular version of each character, that would already set the tone for what was to come. Once the moviegoer has a feel for the character, you can go all out with effects, like Tim Story did with Fantastic Four 2.
So if you're still asking for more character development even after the third movie, then that should be a sign that that director wasn't doing his job in the first place.
