Except they made the 20 minutes time line a big item by counting down the minutes to a certain extent. Anyhow, perhaps the next episode would fit your fancy.Well, I have to allow them some artistic licence for story purposes.
However, it goes beyond simple artistic licence when you have characters whose first reaction should have been to ask, "why is there a space station here instead of the expected prisoner transport?", basically going, "tracking beacon?"...."yup"....."gunship launching"......"Tally Ho, let's kill hundreds of people who may not even know what is happening".
It was bad, because it was thoughtless in its execution. But, like you said, it is my opinion which pretty well goes without saying for anyone who posts here.
