Headscratchers / Star Trek: The Next Generation S7 E24 "All Good Things..."

• The anomaly moves back in time, not forwards, so Future Picard should not be able to see it or affect it after creating it.
  • Especially annoying by how easy it would have been to fix: in the future timeline, they arrive and find a teeny-tiny anomaly, someone comes up with the idea of scanning it with an inverse tachyon pulse to better get a look at it, and POOF! it vanishes. Plot hole patched.
    • The anomaly is noted as being an explosion of time and anti-time, meaning it expands both forwards and backwards in time. The only point at which it would be invisible to the human eye or to sensors would be at or near the moment of initiation — but then the characters would have seen it shrinking leading up to the future tachyon beam's scan and then expanding afterwards, and they would have known exactly what triggered it.
• Exposure to the anomaly's antitime effects causes the crew's cells to reverse their growth and old wounds to start healing — because, basically, they've started aging backwards. Fair enough, but why would this cause Geordi to grow new eyes? His blindness isn't the result of an injury he received at some point, he was born blind as a result of a congenital defect.
  • Q did it.
