Opinions vary when it comes to subjective things like movies so I don't really go by what I "heard" or what the movie critics say but actually experiencing it first hand to form an educated opinion for me.
One fact that can't be dispute is every Transformer movie has made more money than it took to produce and I'm only talking the American box office, not global market or merchandise royalties.
Michael Bay and the Transformer gang look at their critics and just laugh all the way to the bank every time they produce a Transformer movie...
