To be fair, the droplet wasn't exactly a bumper car. It could ram and destroy several ships before your human reaction time could tell which way it went. It went so fast it could pass through a ship leaving a hole behind and white hot metal and it could turn on a dime at full speed.
It was definitely badass, an excellent 'inscrutable monster' type of foe.
I'll say though, the droplet was so far ahead of humanity that it didn't matter what they were prepared for. The droplet could've just as easily been a guided projectile (which it was) and it wouldn't have made a difference.
