OK, most threads about TF4 have been about the actors and robots, but i haven't seen a major thread about this: Both Bay, Walberg and i think others have said that TF4 is very 'different' from the past movies. Now, some of you may say: 'It's just Bay talking s*it, he'll just do the same thing again.' But imagine if there really is a big difference. What could it be? And is the 'it's my most important role in my career' line from Walberg just for marketing, or is it actually special?
