Terra No Way

Terra Nova: Genesis Part 1 & 2

Huge mistake completely took me out of the show.

People are being sent to an alternate timeline's past ( I can accept this). The young nerd of the show explains that they can kill as many butterflies they want without fearing for the future because it is not their time stream.

THEN HOW DO THE FUTURE PEOPLE KNOW IT WORKED.

If time/universe travel is one-way then how does anyone know it is working.
For example if I sent my kid to France and he never came back or wrote a letter why would I send another kid? Even if I sent a police officer to France to investigate knowing I will never find out if the cop found my kid because it's not possible to contact me why would I send more.

The old world is 70% ocean 10% unlivable so there is no way to pinpoint if they landed safely. No evil company or optimistic government would keep sending groups to the unknown without proof of life.

Overall the effects look amateurish, the set looks like a toy set, the plot is Lost with a Stargate, and the acting is underwhelming.
