The focus is on wolverine and he is the main character however you do get a glimpse or two of other old time mutants such as gambit.
This movie could stand alone or with the other X-men movies, I think you could probably see this one first and then the X-men series and maybe have a better understanding of their background.
I do not want to say too much as I would hate to spoil the movie for anyone wanting to see it, I do recommend seeing this movie.
Not a chick flick but there is a few moments of compassion and tenderness, I say this for you guys talking your girl into seeing this movie, so yes, there is a love story of sorts to this movie.
