Optimus prime says that the autobots learned English by reading the World Wide Web.
But then later, megatron gets unfrozen and immediately speaks English.
Megatron has been frozen for thousands of years (they say). Since before there even was an English language. So how does he know English? The first thing he says when unfrozen is “I am megatron,” which is a weird thing to say, period, but also, it’s in English.
This movie is unrealistic.
