This movie is very worth seeing IF you are over the age of 9. The effects are awesome. BUT, the evil decepticons are much more brutal in this one, smushing humans and not caring about the carnage left behind. LOTS more language. The tone of evil is very scary for the little ones. My 5 year old and 4 year old will have to wait a couple years to watch it on DVD. The movie could have accomplished the same story in 20 minutes less time and the plot goes off base here and there(Sam's 'other world' experience with the Primes). Enjoy - but leave the kids at home!
