** Mild Spoiler **
Saw this movie yesterday and was surprised at the number of teenagers who weren't even born when Zoolander came out in the cinema. Some of the girls actually squealed when Justin Bieber and Katy Perry showed up. Made me feel old

Overall it was amazingly stupid and immensely funny in a see it once at laugh at the dumbness kind of way.
As to Cumberbatches character and scene I was prepared to give it a chance on the jokes about "androgyny in modern high fashion" but it just got stupid and went too far. The comments about "hotdog or bun" were crass but to be expected but another character needling Zoolander on how open and accepting he is and would he be happy for his son to be marrying someone like "All" (Cumberbatches character) seemed gratuitous and pushing the idea that "freaks" are ok as long as they stay in fantasy worlds like movies, Fashion, NY, LA and away from your family.
However the fact that no one laughed at all during this scene even the 13-15 year old boys in the cinema was reassuring.
