This episode appears to "borrow" as much from Star Wars as it does from the Star Trek universe, mainly in the space chase scenes and the great music accompanying these and other parts of the episode. Really quite similar to John Williams' scores for a number of action and sci-fi movies, including the Star Wars sagas. The CGI was 100% better than used in previous episodes this season. The bridge(s) didn't look like cartoons for a change!
I really expected there to be a cliffhanger at the end of this episode, but agree because of the renewal of series unable to foresee, it was felt best to not leave the series hanging in midair. Good blend of humor and other emotions present here. Lot of technical terms used, no doubt mixing pseudoscience with current known scientific principles. Good job Seth, writers and rest of crew.
