I love how this series uses flashbacks to connect to the modern world. For example, Johnny's version of how he lost Alli to Daniel back in the 80s. It demonstrates the power of perspective. Speaking of Johnny, he's a complex character, and the most intriguing of season 1. Furthermore, all of the other characters are good actors, and the storylines are interesting to follow. The mother of Daniel didn't quite hit the right notes with me, but this is my only minor complaint.
Lol! Some Star Trek fans can be pretty intense. Read the reviews for a good laugh. It's fine if you don't enjoy something, but some Star Trek fans act like anything that isn't exactly the same as TNG is very offensive to them. Anyhoo, I love TNG myself, and this series grabbed my interest from the beginning to the end. Very enjoyable watch.
