In a word: pathetic. For those who do not know who the Green Hornet is, he is a wealthy playboy who is out to avenge the death of his prison condemned father (by gangsters). His whole persona is a crime lord (and his Chauffer, Kato) looking to take over other crime organizations. He even allows the police and any other outside law enforcement entities to think this. This allows the crime syndicates to really believe he is a criminal instead of an actual crime fighter. Also, the Green Hornet is supposed to be perceived darker than even Batman. The Green Hornet had nothing against killing criminals if necessary.
Seth Rogan. Really? He portrayed an irresponsible, careless frat boy throughout the entire movie. A sloppily dressed, unshaven and a smack talking joke to crime fighting.
Also, Kato with superpowers? What happened to just being an expert in hand-to-hand combat?
The only saving grace of this movie was the Green Hornet's car: the Black Beauty.
What a waist of filming.
