Here's the thing: "Bias" is to say we walked into the theater ready to rate the movie BULLSHIT before it even started. Not the case here, my friend. Even I believed Michael Bay when he said, "I admit the writing on the last was crap because of the writer's strike but this one is going to be good." So I was surprised when the TF3 had all the same knuckleheadedness and stupidity of the stupidity of TF2. I may not be a fan of Tranfsformers as a property but I don't hate them either and I ALWAYS want to see a good movie. However, the Co-Host is a HUGE fan and he came out of it feeling the exact way I did.
Now, HOW is that biased?
As for the "good parts" in that last 30 minutes...JJ, I could list 100 different movies that parts just as good where the whole movie is good or great, not just some bit toward the end that comes after I already hate all the characters.
