What has been missing from the two recent Trek series IMO, is the lack of variety in the stories and storytelling. One story, told over multiple episodes, where that story has not been as interesting as it could have been. In Berman era Trek, there were stand out episodes either conceptually, structurally, or visually. And some of those stories would grab you and linger in your memory. With serialised Trek you may get one or two stand out moments, but could you remember which episode it was from?
