I watched "Alive in Joburg", something missing from the movie... the part the mothership has some kinda of huge cables in the nuclear reactor... So... im guessing the aliens was stranded on earth for awhile since they "re-fueling" their mothership?..
And im confused.. the part, the aliens can make alot (very devastating) weapons and not to mention robots!... yet they do not use them against humans... as humans basically take their freedom away... and not to mention do "experiments" on them...
