Wow, just...wow. The reviewer is clearly an idiot.
When does it ever actually present Hit Girl as in any way "sexualised"? The costume that she wears isn't revealing at all, and infact it's quite baggy and nothing like the skin tight constume that Halle Berry wore in Catwoman. And does the reviewer actually know that school girls do actually wear school uniforms outside of porn videos?!?!?
And as for this mornonic comment:
If it had been rated 12 then i could understand the complaint, but a 15 rating at least shows that it's not being aimed at impressionable kiRAB. The colourful language and strong violence show that, and the fact that it contains such things is evident from the trailer which clearly states that the film "Contains strong language, once very strong, & strong bloody comic violence".
Not to mention that it's not exactly condoning the behaviour when you see how badly the "superheroes" come off after their fights, all bloody and beaten.
