Compared to most films, Spy Kids 4 is great. Compared to the original Spy Kids Trilogy, this movie falls short. One of the major let downs of Spy Kids 4 is that it does not star the classic duo, Juni and Carmen, as the main characters. Instead we're expected to feel some kind of emotion besides disgust for the new main duo who's names I can't even remember. That's when you know a movie is bad.
Overall, I have high hopes for Spy Kids 5: Judgement Day, and can't wait to see where they take the plot.
