I suppose it could be seen that way. However a statement like Transformer fans are stupid and like a stupid movie, makes no apologies about it's intent.
To say the general reception of a film is contrived can mean many things. Zeitgeist for instance. If someone is personally offended by such a remark than all the power to them. What ever reasons you like a film shouldn't have anything to do with why the masses do. Sometimes it may but that's out of your hands. If I like Obama, that doesn't mean I have to feel slighted by the idea that a lot of his momentum/early reception came from a movement. If I like him, I like him.
I happen to think the film was good but overrated. I may have been one of the few people in my theater that didn't snicker or shout out when characters took unnaturally long pauses instead of offering simple responses time and again. The elevator scene got roars of laughter for it's out of nowhere tonal extremity but again I found much more compelling when it was saying something rather then when it literally wasn't. The subtlety had fans reaching for explanations such as the driver was mentally challenged and such things. I think that's where it failed the most. If it actually made a stance, it wouldn't have divided the audience in the way that it seemingly has. But that's me.
I think if people talk of JGL performance as being amazing in this, it will be because he gives the audience a lot to digest, from channeling Willis, to being a killer vs being hunted and arching and so fourth. He won't rely of the plot to tell his "story of redemption" or whatever for him.
I do think JGL and Gosling represent the next gen though. Infact, every now and then I imagine them swapping roles. Gosling in inception and Levitt in drive. Gosling in 500days and Levitt in notebook. It actually works.
