Can do - build time shift machine to send people back to Jurassic Park
Can't do - fix pollution, build a gun that kills dinosaurs.
The impression I got wasn't they built a time machine, but they discovered a rip in time to an alternate universe and couldn't control the fact it was 85 million years ago.
They just tried to take advantage of that anomaly.
I hope they explain the portal (or whatever you want to call it) is in fact a two-way rift. If it's one-way without no way knowing what happens on the other side, how did they know it's 85 million years into the past, or an alternate timeline, or Sgt. Avatar
