ELI5: What was the point of the Gunpowder Treason and Plot and why do people celebrate it if it was a failure?

Also known as Bonfire Night, Guy Fawkes Day, the Fifth of November, and so on.

In the 1600's, England was ruled by a Protestant Christian monarchy who didn't take kindly to Catholics.  A small group of Catholics (Including Guido "Guy" Fawkes) decided to blow up part of the Parliament building, killing the King and making it easy for them to put a Catholic Friendly leader in charge.  They rented out a cellar underneath the building and filled it up with gun powder.

Someone in this conspiracy sent an anonymous (heh) letter to a catholic who would have been in Parliament that day, telling him to stay away.  This guy went to the authorities.  The grounds were searched, and Guy Fawkes was found guarding the gun powder.  They took him in, tourtured him, got the names of all the conspirators, brought them in, executed them, and nothing blew up.

They celebrate because Parliament didn't blow up.

It'd be like if we stopped the 9/11 hijackers and made a holiday out of it.
