I was at odds with myself in my opinion on Michael Bay as a filmmaker after I saw ROTF. In both films on the whole I really enjoyed the action sequences, which Bay had a lot to do with. However, such elements as the amount of humor, the tone, and characterization are things Bay could improve on. Thinking about it, I came out of TF1 very happy with the Autobots' development; all of them. When Jazz died I actually felt bad (compared to me not caring at all when Jetfire died or Arcee maybe died), and I felt all of the Autobots showed a great extent of teamwork despite the focus being on Prime and BB for obvious reasons. The tone was also much more consistent and enjoyable than the erratic tone in ROTF, and the humor, while in plenty, did well beause it was more situational and not as forced. So, why did things change so much in the sequel? What I think: Everyone, Bay included, had a big challenge on their hands with the first film. Before Transformers became two summer blockbusters it was a cartoon and toyline. Everyone knew if this was to become a high-grossing film SERIES, the first film would have to set up the universe in a way to appeal to fans, non-fans, and most of all the average movie-goer. Even Bay said that by doing things very real in terms of effects, that woulld be the wow to the audience. If the concept did not click, then TF would be done as a film franchise. So in that respect Bay knew that while it was his film, it was going to take the input of many to get this right. Now, in ROTF, the universe had already been successfully established. Everyone was on board with the concept, so I guess Bay felt he could have much more free reign with characters (ie, creating the Twins and killing Arcee just because of his fancy), including more sexual humor, and more giant explosions. While he always parades "a Michael Bay film" around all of his movies, I think ROTF felt more like the general Bay movie than the first offering. In conclusion, I would like to have him back for TF3 but only if he would make the film more of a collaborative effort than "his baby", which unfortunately I think is doubtful. It's sad when you read these interviews with Bob Orci and Alex Kurtzman in which they're not even sure if Arcee is dead or not, and have to apologize to everyone the Twins offended. When the writers aren't even sure what's going on, you know something's wrong.
