I am reviewing "Race to Witch mountain".  the effects were outstanding.  the mystery and action was constant from the start and never stopped.  The humor was also very good.  the humor was just enough to keep me from being too tense from all the action.  I also loved how they added the two people who played "Tony" and "Tia"  into the story.  their parts were small but significant.  this is a must see for everyone but it helps to watch "Escape to witch mountain" and "Return from witch Mountain"  as they are referred to in this movie.
