Hmmm....quite a lot to think about there.

Regarding the soundtrack, I agree with STL. I think the '86 soundtrack to be superior.
I haven't heard the '07 'soundtrack', but the score is quite forgetable. Steve Jablonsky is no Bernard Hermann, Jerry Goldsmith, or James Horner. I have to agree with Jay in that the '86 soundtrack is cheesy...but a bit of cheese here and there is fun (except that horrid title track).

I also agree with Jay's summarization of the '07 movie. I enjoyed the film the first time because my expectations were so low, but since then, I find it extremely hard to watch the damn thing. I find myself just skipping to the transformers...you know...transforming. THAT was cool. Too bad about the rest of the movie.
It's true both films are essentially extended ads ('86: toys, '07: GM cars), but at least the '86 one had depth. And quotable dialogue.

But, hey...whatever people enjoy is fine by me...I'll be a closet elitist. :P
