Input: Verify if the sentiment of the following document towards the entity Rick Grimes is Positive . The season eight premiere -- and 100th episode -- of "The Walking Dead" begins with  Rick Grimes  apparently daydreaming in the heat.  He  pictures flowers in a peaceful room. In reality   he 's at Hilltop  staring at a grave while preparations are being made to harden vehicles.
 Rick  addresses  his  united group of Alexandrians  Hilltop residents and Kingdom subjects  riling them up about their right to take back what's theirs.  He  vows that whoever tries to stop  him  will meet their end  though there's only one person who has to die: Negan.
 Rick    his  eyes lined with red  again pictures that flower-filled room ... and  himself  in a bed   his  face overgrown with a long grey beard.
"I'm sorry " Negan says  "I was in a meeting." He tells  Rick  he knows he's currently outmatched  and he won't sacrifice his own people.  Rick  offers for Negan and  his  leadership to surrender  and only  he 'd pay the price.
 He  then reveals that Gregory  the head of Hilltop  declares  his  allegiance to Negan  and demands any Hilltop people surrender and return to their homes.
 Rick  again tells Negan's people to surrender.  He  counts down  before opening fire at "seven."
 Rick 's gang wastes a tremendous amount of ammo firing at windows before moving their fortified cars to better positions  while Daryl's gang breaks up into groups  with  him  hopping on a bike to lead the horde toward the Sanctuary.
At Sanctuary   Rick  uses the RV as a car bomb  blowing through Sanctuary's outer defenses. An injured Negan hobbles out from the main building. Rick fires in vain; although he's pinned down  Fr. Gabriel urges him to flee. Rick snaps a Polaroid of the pinned-down Negan and leaves.
Output:
yes
