Now Kato was originally played by Bruce Lee in the TV series and we all know how great he was. In this adaptation he's played by Jay Chou who clearly is no Bruce Lee but he carries himself well given the fact that Seth Rogen is basically a spotlight whore throughout the film, giving himself ample amount of lines that he believes are humorous. That's what happens when you get the main actor of the film to get on board to commence the script. He's just awful, plain and simple.
So now that Britt and Kato are integrated in a "bromance", they get an idea to fight criminals while impersonating a criminal and his sidekick. The crime boss of the city is Chudnofsky(Oscar Winner Christoph Waltz) who provides the film as only a villain and not a character.
Now one thing I liked about this film is that they follow the Trendle's and Striker's storyline rather than modifying it, points for that. Any true fan of The Green Hornet should be familiar with the events leading up to the film's climatic scene. But who cares, you won't feel gratified with the work that was put into it. Gondry will always be remembered for his film "Eternal Sunshine of The Spotless Mind", although I think "The Science of Sleep" is more animated, and I think it's safe to say this is his worst film up to date. Will he be able to redeem himself? We'll have to wait.
