I went to see it and thoroughly enjoyed it. Yes it is historically inaccurate, but it isn't based on historical fact, its based on a graphic novel, yes it looks fabulous, yes it is a bit silly at times, and yes there is a lot of buff male torso on show.
What's not to like?
I know Mark Kermode was fairly scathing, but he has a job to do, as a critic. I merely go to watch films for pleasure, and I find rows or gleaming sixpacks thoroughly enjoyable.
