"Felt like a novella wrapped around a Google ad."
The strange mix of fictional corporations, historical characters, and fonts with bizarrely overwhelming mentions of GOOGLE GOOGLE GOOGLE annoyed me. Leveraging all of Google's power was a quick way to illustrate some of the efforts, but lauding their cafeteria, management structure and general nerd culture to the degree and pages he devoted to it was unnecessary. The resolution also angered me for reasons I can not describe without "spoilers".
The characters, other than his caricature of a "quirky nerd girl" girlfriend, were likeable. The mystery wasn't really that mysterious, but the natural way the story was told made it feel more friendly and enjoyable.
He does an excellent old man voice.
It could be properly Wes Anderson-ed up to be enjoyable, but it would really depend on the director.
