Jon Hastings of The Forager Blog has a problem with the ramshackle plot of Art School Confidential, but his problem isn’t that there was too little plot, but too much. Ah, let him explain it to you. FWIW, I disagree about whether this point made the movie lousy–I laughed as hard at it as I’ve laughed at any movie in years–but since it seems to be a sticking point for many people who see the film and since Jon approaches it in such an interesting way, you should probably check it out.
In theory, at least, scientists believe they are capable of constructing a Harry Potter-style Cloak of Invisibility. Science is awesome.
