I don't think the talking was a bad thing... it shows that the audience REALLY responds to a film. If the audience hates the film, they will either laugh at all the wrong places or they will moan about how they hate it or "here we go again."
Not the case with Transformers... I have never really experienced a film like this before and I can only imagine the 80s films such as JP, Back to the Future and the first Batman may have had this type of an experience.
The audience loved it and obviously loved it ALOT. The reaction was HUGE. Hell, I'm usually one that is able to restrain myself during movies, I never talk or really react with the crowd that much- here, I couldn't restrain myself. I think I said, "wow" a couple of times- not sure because there was a lot of loud reception all around me. But, I think this movie caused me for the first time seeing a movie to verbally respond... it was that kick ass!
The scene that did that was the first scene Optimus meets Sam. I had a massive fangasm during that scene and had to try to keep my excitement at bay because of that. Lol. And something interesting to note- I never watched the cartoon, I only played with the toys when I was younger and read and loved the screenplay. So, I can only imagine those who did watch the cartoon back in the day and how they responded to that scene.
Because, let me tell you- you don't need to be a die hard TF fanboy to get a fangasm during many moments in this film. I could, even though I wasn't old enough to see it in theaters, probably say JP would have had a similar reaction from the audience... there's just something very universal about the concept, whether you watched the cartoon or not.
