This show is Funny People meets Scott Pilgrim and the Mask. It is full of great action, witty and snarky dialog, and plain ridiculousness.
The special effects were amazing, but the characters don't really progress. If you're looking for some thing fun and shallow, this is the movie for you.
As fun as the Green Hornet character is, it is Kato that makes the whole movie worthwhile with all of his inventions and his progression as he helps the lame 'hero' have one moment of cool action.
