Why is it pointless? Are you saying a male movie critic can't form an opinion of the merits, or lack of, of a movie with a different gender target audience than his own? That's nonsense.
Truth is, we're at the dawn of the pink novel/literature movie period. First it was Twilight that meshed pink novel genre with vampires and now there's 50 shades which mixes the genre with SM/sub-dom themes. Both poorly written but worldwide book bestsellers nevertheless due to their fresh spin on the genre, and the same can be said about the movies it seems. They're utter crap but make a ton of cash in the box office.
Frankly, i don't know why people keep associating quality with box office results. Let's face it, in a few years, half of these blockbuster successes will be just an embarrassing memory to most of the people who watched them when they came out.
