I was thinking of Twilight. Was the choice of actors, location, fight directors etc. relevant to the success of the movie? Or was it down to the plain jane Mary Sue the viewer could inject themself into that a sexy vampire was in love with for no real reason? (And in the sequel, a sexy werewolf is also in love with Mary Sue for... ...reasons?) Like, I feel you could've cast this movie entirely differently, or had a different director, and so long as SexyWishFulfillment McVampire was good looking enough, you'd make bank, so long as you catered well to the demographic watching this dross.
