Re: Transformers 4 is going to be AWESOME.
The best shot fights I think were in the last one, however ROTF had the most tangible stakes. The forest fight, the rampage fight. Very immediate stakes, usually life hanging in the balance just below them. Otimus outnumbered an in serious danger..etc.
A movie about a man learning to be Superman will finally get the GA invested in the premise, while at the same time piss off people that want what they want. If only the latter group showed up for the last movie.
