The 2nd installment is practically identical in formula to the 1st but amplified to the point of boredom. The jokes are more plentiful, more cute pets, the girls are more sexy, the explosions are er uh.. more explosive, more Autobots, more story-telling based on the Autobot's history, more chase and battle scenes, improved audio FX. With all of this we get less character involvement, drawn out battles that play out way too long, and a rushed epilogue. Not a BAD movie in any sense but numbing to the point of boredom due to relentless action. Some clever writing and story telling from a film of this genre, it carefully avoids cliches and sappiness, and posing is kept to a safe minimum, but a good 20 minute trim would have helped enormously.
