Pit and Pendulum ending

I think the Pit and Pendulum should end alot better than it did.  It ended with someone just rescuing the man.  That's boring.  I think it should have had something to do with how he tries to escape from the heated walls.  Maybe there could be like a trap door hidden in the floor that he finds and he somehow finds the trapdoor and escapes.  I think that would be a much better ending.  And to add suspense and fear, he should be frantically searching for a way out and even get hit and burnt with one of the walls once or twice.  Just as soon as he is about to get squished in between the walls he finds the trap door and escapes forever.
