Guillermo del Toro's Pacific Rim, a movie about giant robots that fight giant monsters, is a little over two hours of pure sugar. If you are in the mood to eat pure sugar, you will most likely enjoy Pacific Rim. I am not saying this flippantly - as in, "only a bad person would enjoy sugar." Everyone likes sugar. But not everyone is in the mood for sugar. And a lot of sugar can make you sick. If you are in the mood for something that's a little more substantial than a Pixy Stick, you might not like Pacific Rim.
Not that you needed further proof that 2012 was going to be the year of Lizzy Caplan, but the actress steals her scenes in "frankie go boom" with the fervor of someone trying to become your next favorite indie queen. She manages to lift what could have been a rote comedy of sibling rivalry and escalating embarrassment into something heartfelt and human.
