Query: Actually quite good

This was one of those movies that I avoided at the theaters when it first came out. But my children wanted to see it, so we rented it, and wow, was I taken back. This is actually a very funny movie. Starring mostly lesser name actors for the human characters, the guinea pigs are voiced by stars such as Steve Buscemi and Nicholas Cage. The story is quite a simple; two scientists develop technology that gives human intellect and speech to small animals such as flies, guinea pigs and moles. These upgraded animals are then used to fight international crime and terrorism. This movie is part action, part comedy, and part adventure. The special effects are kept low-key but they are effective, especially the movement of the animals. The dialog is quite engaging, with each of the animals having their own unique personalities, attitudes and slang. Best of all is the storyline, which keeps you guessing to the very last minutes of the movie. Overall, quite worth the watch.
