Not allowed to take comedy seriously?

Manohla Dargis gave a detailed, serious minded critical review of the latest crude movie by the wealthy, but tragically stuck as a permanent 14 year old, Seth MacFarlane (the move being the not particularly well performing Ted2), and people (including Steve Sailer) are mocking her for it.

I dunno.  When a movie features an attempt at humour described as this:

Mr. MacFarlane’s fixation on anatomy is especially striking and reaches its nadir in a scene at a sperm bank. There, John accidentally knocks over a shelving unit and ends up splashed with ejaculate that, a nurse explains, has been excluded because the donors have sickle cell anemia. As John writhes, Ted laughs. “You’re covered in rejected black guys’ sperm,” Ted says. “You’re like a Kardashian.” Mr. Wahlberg plays the moment with the right level of desperation, but Ted’s lines are depressing and desperate. 

I don't see at all what is wrong with some serious discussion of what is meant to make comedy funny.  This section by Dargis is spot on:

In “Ted 2,” he generates squirms, largely because his humor is so tone deaf. A Freudian might enjoy trying to figure out if his repeated references to black male genitalia represents a fear of black (male) power or something a wee more personal. And Mr. MacFarlane may believe that mechanically reciting words will drain them of their force, which superficially recalls Lenny Bruce’s idealistic claim that the repetitive use of a familiar racial slur would do the same. “The word’s suppression gives it the power,” Bruce said in 1962, “the violence, the viciousness.” History has proved otherwise, and the word, its violence and viciousness are still with us. I think that Mr. MacFarlane knows this, and that’s why he cast a few well-known black actors in authority roles, as if to signal, wink-wink, that the race stuff is just all in good fun.

She talks a lot more about the race aspects of the attempted jokes.

There is nothing wrong with a review of this kind.
