Ralph is unimpressed because he lost his chance to signal a boat. While the hunters were hunting the pig, Ralph saw a ship on the horizon, but the twins and jack, all responsible for watching the fire, were hunting and no one was on the mountain to keep the fire going.
There are many possible ending which could have been used in either of the movie versions to change them from the endings which were actually used (essentialy the same ending as the novel). For example Jack and his hunters could have killed Ralph. Alternatively Ralph could have killed Jack and then the hunters could either have adopted Ralph as their rightful leader or killed him in revenge. The entire island could have burned and killed all, or some, of the boys.

The main characters of Lord of the Flies are Ralph, Simon, Jack, The Hunters, Piggy, and Samneric. The other characters are The littleluns, Maurice, Robert, Percival Wemys Madison, Johnny, and Henry.
Ralph tried to decide which option was best, either climb a tree and hope not to be spotted, burst through the line of hunters or hide and hope that they would pass without finding him.
In chapter 8 of "Lord of the Flies," Ralph characterizes Jack's hunters as primitive and barbaric, with an emphasis on their violent tendencies and detachment from civilization. He sees them as being consumed by their bloodlust and becoming more savage as they embrace their roles as hunters. Ralph is disturbed by their descent into savagery and the way they prioritize hunting over maintaining the signal fire and runway.
