The theme of today is not following your own advice. To best illustrate it I chose the movie The Prestige which I've recently seen and which had some critical acclaim and a high rating on imdb. Btw. everything following is kind of spoilerish.
Oh did I mention the entire conflict of the movie is based on sheer stupidity? Why did he have to tie a knot that was hard to untie? You have a magic trick, an illusion, make believe... and you have a knot that looks complicated but is fairly simple to untie. So why in God's great name would you actually tie a hard one? Moreover why would the person actually risking to die encourage and tease you? You guessed it, a stupid bitch dies... and the whole story is an ever-growing series of revenges.
The only good thing about this movie is the characterization of the 2 magicians and the acting, with the fact that you don't know which of them is actually going to win being a big plus.
A much better movie, although still kind of stupid, meaning the story is supposed to be a mystery and it is clear what is going to happen about ten minutes in, is the Illusionist.
For more on failing at what you profess, stay tuned.
