What the %@#! is a Reboot?

Seriously.  I'm tired of this trend.  I read today that the Bourne movies are getting a reboot.  I just don't understand what it is.  The first Bourne movie came out in 2002.   That's 8 years ago.  How can you already be rebooting it? There was nothing wrong with the franchise in the first place!  With this, Spiderman, the countless horror flicks, and Superman, X-Men and everything else, I'm fucking tired of it.  Yea the third Spiderman movie was a complete turd but what you do is hire another director and start fresh, like Batman did.  But you don't do it 10 years later! The first Batman movie (the Tim Burton one, not the Adam West one from the 60's) came out in 1989.  Batman Begins came out in 2005.  That's over 25 years later, and 10 years after Batman & Robin, a film which affectively ruined filmmaking in general.  25 years is plenty of time to reboot a franchise that is struggling.  10 years is not.  Fuck you hollywood.
