Has it really taken this long to figure that out? Jackman, although a decent actor, was only cast in the first place because of that love triangle between Logan, Cyclops and Jean Grey in the original X-Men (and he wasn't even the first choice: that was Dougray Scott, who had to drop out because Mission Impossible: II ran over schedule).
A true-to-the-comic Wolverine wouldn't work because Jean Grey was unlikely to fall for a hirsute forest man half her height. That's why he morphed into a more conventional leading man type embodied by Jackman.
If Darren Aronofsky is really that committed to getting Wolverine right, they need to start from scratch (pun intended)...but that's not going to happen, because most of the movie-going public now see Wolverine as a watered-down romantic lead. All for the sake of cramming in an unnecessary romantic sub-plot.
Thank you Hollywood.
