Transformers was great. Transformers two basically rubbish. How was Transformers 3?
Plotline: Involved the idea that the US went to the moon because of Transformer technology spotted there. Sillier than Transformers, but much better than the annoying Transformers 2.
New Robots: Nothing spectacular really.
New Megan Fox: A much worse actress (seriously; this is possible) and possibly with an even weirder looking face.
Optimus Prime: Much less of a wuss than before – more like a robotic Arnie in Commando.
Ending: Derivative, but, again, miles better than Transformers 2.
Verdict: Don’t bother making Transformers 4, unless you can use Shia going to seem fun again like Pirates 4 did.
