Great idea (the column)... been looking forward to it. I would recommend that you include the article's title in the thread title as I suspect this will be the first of many, e.g.
The Soapbox I: TFM or TFTM
The Soapbox II: What is a Scalper? ()
That way, the resulting discussion will be compartmentalized and future columns won't be drowned out in page 9 of a never-ending thread.
Now, the meat.
I disagree with your analogy of the scores/soundtracks. I find the TFTM soundtrack makes me cringe as if I'm watching Ricky Jervais give his career performance. The music is so dated, so cheesy, so cheap. On the other hand, the TFM soundtrack is simply a payola joke. Lastly, the TFM score is decent, but also loaded with cheap musical tricks. So to me, all three are poop, with the TFM score being the least poop. A few musical scores that I can think of off of the top of my head that are vital contributors to the films that contain them, are Aliens, Gladiator and Batman Begins.
With the exception of the soundtrack, I adore TFTM. It was mind blowing to me as an 11 year old. It introduced mortality (on a planetary scale!), the death of lead characters, and a completely new cast, including the almighty Unicron (do you think Spaceball 1 was influenced by Unicron?). To me, it was as profound and as powerful as The Empire Strikes Back.
TFM employs the standard Hollywood playbook for quick money: Special effects, tits, popular music and bad jokes based on contemporary culture (Prime: "my bad"). Unfortunately, that means it also comes with flawed science (Maggie/hacking/viruses), wasteful unnecessary scenes (Autobots at the Witwickys), incomplete special effects (too much blur), some glaring plot holes (Barricade), and an anticlimactic ending (uh, touch the bad guy with the Allspark). Knowing Bay, I knew it was to be exactly like that, so my expectations were lowered, and I still like it, but I'm sure that's due to my emotional ties to the franchise, as it is just Hollywood smut.
