Congratulations. You've just described TRANSFORMERS as a concept. It was never that deep.
I'm curious, what kind of depth did you expect this movie to have?
How was TRANSFORMERS specifically condescending to the audience? And realize...there is a difference between not being brilliantly written, and being condescending. TRANSFORMERS, as I recall, didn't feel the need to beat the audience over the head with what was happening, like, oh, say...BATMAN BEGINS?
Didn't need, didn't need, didn't need...Welcome to Hollywood in 2007/2008. This is our culture. There are people who RESPOND to those kinds of stimuli, as evidenced by the braindead songs that are most popular, and the braindead shows that are popular. It's the same reason Batman has to crack jokes in BATMAN BEGINS, or we get nonsense like "I have got to get me one of those" or "DAYUMMM! NICE CAR!". You think TRANSFORMERS is the only place it shows up? Think again. There are also people who act like the characters found in TRANSFORMERS do, and yes, some of it was absurd, but what world do you all live in that you've never met someone like those characters at some point?
Gosh. I wish I cared enough to argue PIXAR VS TRANSFORMERS. I don't. The people at PIXAR tend to do something very right, seemingly in a vaccum. Good for them.
Look! Hyperbole!
I don't know what to tell you. This "sudden melodrama" is how movies work, and it's not new. I don't tend to give a fiddle when characters die. TRANSFORMERS never advertised it as a truly major event, you just seem to want it to have been. This isn't the Death of Optimus Prime we're talking about here.
What do you want, something that makes you tear up because a robot died? A robot funeral?
You want Jazz to say something witty like "Prime...don't be afraid" before he dies?
Good god...go study humanity. People use humor when they are afraid. Constantly. And humor has almost always been used to lighten an otherwise serious scene in action/adventure movies. You ***** about its use here, and you may as well go down the list of adventure films, because trust me, you'll find it there, too. It's a film convention, not something unique to Michael Bay and TRANSFORMERS.
