Q: What is the sentiment of the following document towards the entity Django Reinhardt ? The leader of the band is Django Reinhardt  the incomparably gifted Romani jazz guitarist  soulfully embodied by the French-Algerian actor Reda Kateb. He's biding his time in the French Alps during German occupation  hoping for stealth passage across Lake Geneva into Switzerland. One of the men throwing punches is a Nazi solider  which means the inevitable: a lineup  a lockup and the sternest of warnings.  Reinhardt  is no good  it would seem  at laying low.
 Django  isn't really a biopic  despite the implication of its title: There are no misty flashbacks to  Reinhardt 's childhood stealing chickens in the French countryside  and no scene depicting the caravan fire that badly damaged  his  left hand (though  his  two mangled fingers do come up for inspection). The film is more of a fraught character study  a portrait of the artist under pressure. Comar  best known as a writer and producer of the 2010 film Of Gods and Men  brings admirable restraint to his directorial debut  keeping the stakes high and the focus taut.
 Reinhardt  is a laconic and reluctant hero: "This isn't my war "  he  growls  citing allegiance not to a flag but to a Romani's coldly pragmatic ambivalence.  Django  charts  his  awakening to the horrors of the war â notably for  his  people  whose mass extermination imbues the film with a self-righteous  lugubrious air. Comar is more effective with uneasy proximities and grim capitulations  showing how complicity can form through a series of slippages.
But the film's story â loosely adapted from Alexis Salatko's novel Folles de Django â manages to feel at once oversimplified  underfed and overburdened.  Reinhardt 's personal evolution is clumsily tracked in dialogue with a former mistress who has suffered unnamed violations at the hands of the occupiers: "You're the only person this war hasn't changed " she says bitterly to  Reinhardt . (She later rescinds the charge.) A climactic set piece at a Nazi banquet feels pat.
It's not inherently a problem that Comar does less with plot than he does with imagery: There's vivid poignancy in his depiction of the mass evacuation  and in  Reinhardt 's desperate flight through the snow. But by all accounts â the most authoritative being Michael Dregni's excellent biography Django: The Life and Music of a Gypsy Legend â Reinhardt was even more conflicted during the occupation than this film makes him out to be.
And what's meant to be a wrenching coda â the post-armistice premiere of an organ mass called "Requiem for Gypsy Brothers" â is marred by the wan pathos of the music itself  composed by Warren Ellis. As the piece plays   Reinhardt  stands dumbstruck  overcome. But if we're supposed to believe this piece represents the peak of  Reinhardt 's emotional expression  the point is discredited by earlier musical evidence. In a film that's so often about taking sides   Django  can feel at war with  itself .

Q: What is the sentiment of the following document towards the entity David Shulkin ? In a letter to U.S. Rep. Tim Walz (D-Minn.)   Department of Veterans Affairs Secretary David Shulkin  said VA’s ability to research medical marijuana is hampered by the fact that the drug is illegal federally.  Shulkin ’s letter came in response to an inquiry by 10 Democrats on the House Veterans’ Affairs Committee. The letter asks  Shulkin  to commit the VA to investigating whether medical marijuana can help veterans suffering from PTSD and chronic pain and identify barriers to doing so.
“VA is committed to researching and developing effective ways to help Veterans cope with post-traumatic stress disorder and chronic pain conditions ”  Shulkin  wrote in a response to the members of Congress. “However  federal law restricts VA’s ability to conduct research involving medical marijuana  or to refer veterans to such projects.”
“VA’s response not only failed to answer our simple question  but they made a disheartening attempt to mislead me  my colleagues and the veteran community in the process” by stating that the VA is restricted from conducting marijuana research. Walz  a veteran  said he plans to send another letter to  Shulkin  asking for further clarification.
A spokesman for  Shulkin  pointed to the secretary’s past comments on medical marijuana.  Shulkin  said in May  “My opinion is  is that some of the states that have put in appropriate controls  there may be some evidence that this is beginning to be helpful. And we’re interested in looking at that and learning from that. But until the time that federal law changes  we are not able … to prescribe medical marijuana for conditions that may be helpful.”
 Shulkin  said VA is offering a suite of alternative treatments for patients with PTSD  including yoga  meditation  acupuncture and hypnosis. The letter also said VA has a program to reduce the amount of opioids prescribed to patients with chronic pain; since 2013   Shulkin  wrote  33 percent fewer patients were receiving opioids.
