Example Input: Verify if the sentiment of the following document towards the entity Luke Cage is Negative . Netflix just published the new âDefendersâ series  the culmination of several years of work by Marvel Television to get Marvel into prestige serial storytelling. (We have to find a new word for this: we canât call it âTVâ much longer.) The Marvel-Netflix deal now includes two seasons of âDaredevil â and one each of âJessica Jones â âLuke Cage â and âIron Fist.â Thatâs 65 episodes  plus the new eight-episode âDefenders â around 50 minutes each. Thatâs more than 60 hours on screen in the last two years.
Now  you can blame whatâs wrong with âThe Defendersâ on the Marvel shtick: America has no enemies but its own divisions. The heroes inevitably fight each other. That could work if you had writers who understood Americaâs divisions  but itâs disastrous when all youâve got is pettiness and liberal identity politics. âThe Defendersâ does better than any Marvel movie to give you thrilling fights  however. At least Daredevil does;  Luke Cage  is also pretty good; the other two were deficient to begin with and apparently not getting better.
There is a deep argument hidden somewhere in this mess of a story. But to see it develop  the viewer has to ask himself: why is Daredevil so scared of his own heroism  which might lead him to kill people? Heâs a Catholic  of course. And weâre reminded of that in an important scene in a confessional. But whatâs the import of that fact? Why is  Luke Cage  telling a grieving mother  he  learned about the power of prayer from  his  own father?  He âs an heir to MLKâs sacrifice and hope  as we know from  his  own show  but why does that matter here? The evil guys  too: why is their quest for immortality so evil or wrong? We all want to live as long as possible  anyway!
Instead  we get this mess of American social pathologies of individualism and evil ninjas. This is worthless for articulating the fight between two worlds  one dedicated to equality  the other inequality. Maybe future stories will get better. A friend pointed out that thereâs a lot of Christianity in the first season of âLuke Cage â and the second season is supposed to be more serious about civil rights. He also pointed out another sign of hope: civil rights are connected with the Second Amendment.
In my previous essay  I said high-flying civil rights rhetoric collapses in âLuke Cage.â Behold: in an emotional moment mid-season  Luke Cage tells a young black man-turned-criminal about Crispus Attucksâthe first man killed in the Boston Massacre of 1770  and thus  the first martyr of the American Revolution. He was black. We see his legacy exploited by a gangster and a politician  who abuse Harlem while pretending to save it. Unlike Attucks  they always put themselves first  because when they were poor  weak  and needed protection  nobody put them first.
 Luke Cage  takes a shot to the head from that stupid  scared young criminalâbut it makes no dramatic sense  with a literally bulletproof hero.  Luke Cage  is no Crispus Attucks. Our stories fake sacrifice  and thus betray our deepest awareness of our neediness. Thatâs because of our politics and our fear of death.
Example Output: no

Example Input: Verify if the sentiment of the following document towards the entity Mitt Romney is Positive . By comparing the responses from both Romney and Gingrich , it is evident that Mitt knows much more about the housing market then Newt does . 
Mitt is good at this , too , as mentioned before except he just has to avoid sounding too much like a businessman that he is . 
And , once he 's gotten that point across , policy professional Mitt flips the subject around , landing with an attack on Newt 's ties to Fannie Mae and Freddie Mac . 
But , then again , Mitt just had to sit back and let his rivals self-implode on their own -LRB- do n't worry , we put in the Rick Perry "Oops" video after the jump -RRB- . 
He may have completely -LRB- and blatantly -RRB- changed his mind on abortion but it 's a rare occasion where , pleasing his greatest criticism , Mitt acts like a human being who laughs , sulks and cries whenever he watches My Dog Skip .
Example Output:
yes
