This episode is really bad. Let me try to explain so without giving too much away. First of all, there is not so much suspense and it feels quite boring, but okay; that can happen, and suspense has never been the primary focus of star trek. However, no interesting moral questions are raised, nor are any interesting scientific/futuristic concepts presented. In fact, the concepts presented sound like those of a 5 year old. Let me summarize these concepts (I hope this doesn't count as a spoiler): if you travel past warp 10 (a threshold this episode suddenly came up with; and is not adhered to in some other star trek canon) you are everywhere, but apparently also at different points in time. Slowing down will make you miraculously pop up very close to where you left when you went to warp 10. Rather than traditional evolution which happens over many generations, if you are everywhere and at ever moment in time, your DNA suddenly changes to whatever a human ancestors or successors DNA looked/will look like at some specific time in the past/future. Even my dreams are more logically consistent than this episode. Everything that happened in this episode feels completely random.
