Then the second half went to poo. The teenager abandoned his little sister when she needed him the most. The alien's laser beam was replaced by sucking human blood. It was never explained why. The aliens traveled light years to arrive on Earth just so that their machine could be easily chopped up by earthling's puny axe. The aliens with advanced technology did not know about different planets had different bacteria that could kill them. Finally, the teenager survived without a scratch and everyone was happy, completely forgot his abandonement. ⭐⭐
Overall, ⭐⭐⭐. Worth a watch if it's free.
