I'd love to see a live action version of the animated movie sequence right before he fights Megatron, with the whole smashing through Decepticons and bursting into robot mode with flames out the fuel tanks etc..
Just thinking about that scene gives me goosebumps.

 

I agree. Nothing makes me pee my pants more than that part where Barricade rolls on his side, then transforms to alt mode.

 

I laughed more than I expected at the Blackout transformation at the end.

"Oh wait no, it's a helicopter again, stop shooting"

 

Now that would be a nice "touch"
