A fun action movie with lots of great-quality special effects. Definitely lots more special effects and cool transformations than the first one. The further character development (revelation) of the whole Primes history (especially if you didn't know it beforehand) was very well done and quite interesting. It was sometimes difficult to tell who the good Autobot was versus the bad Decepticon when they were fighting (they looked similar). You definitely get your money's worth - as the movie is a solid 2-1/2 hours of action adventure. If you liked the first one you will love this next chapter.
