Nobody wants him back. The previous movies altered the origin of the alien and weren't popular or successful. Romulus is an attempt to go back to basics with what the fans want, and that doesn't include the David character.

Not really anything like the villain she fought in transformers, one is a gigantic robot that can turn into a vehicle, the other is a female android.

The fact she played two different roles which vaguely are about the similar topic of robotics is called "acting" and is what actors do.

Must be a slow news day at screenrant huh?
