We loved the first movie but this one just didn't meat up to the bar.  The first movie blew you away with the amazing graphic effects, which this one (Transformers: Revenge of the Fall) had as well, but it was lacking in other areas.  I was negatively surprised to hear the actors using profanity much more than they had before.  The humor was based on sexual inuendos (the pet dog and robot kept humping peopl'es legs) and just wasn't funny to me.  The first movie had better clean humor and was genuinely more funny.
