actually, probably movie Gwen too, but then movie MJ just bugs me
That's probably because Movie!MJ is basically 616 Gwen - at her worst written - with red hair. Ultimate MJ is a little guilty of this, too, being the "bland" girlfriend to the more interesting Ulti!Gwen (or my fave, Ulti!Kitty).
I really dislike how other continuities seem to try take MJ some kind of composite character. That never works. (And I say this as someone who likes Gwen!)
