I guess I totally agree with you the article didn't really give a fair idea about the manga. My first surprise was actually when he wrote he thought it was a yaoi manga and there were too much hints toward SebastianxCiel. I actually never even considered the manga to have much homoerotic stuff... except for Grell that is. (The rest is just teasing...? Maybe a bit lovey-dovey...? But certainly no yaoi for as far I look. I guess there's as much yaoi as you want there to be.)
And well, since he apparently thinks is BL and doesn't like BL, he just says the whole manga is terrible. He's allowed to have his own opinion, but he might have considered to say something that didn't come down to: "You'll love it if you love yoai, if you don't love yoai this is just rubbish." There's also something in-between there. People who just enjoy the series because Sebastian is so incredibly perfect and hot? Or because they think Ciel has an amazing personality? There's much more reasons than yaoi to like the series.

Anyway, the poster is making up a little, but the article is just rubbish. (Come on, if the series was really that bad, why would they still publish it?)
