An okay episode, but I spent the whole time racking my brain to try to remember where I'd seen the main guest actress (Tiffany Smith) before. It took so long because I was trying to think of what show I'd seen her in, but I finally remembered that she was the host of various DC Comics-related news segments, interview videos, and specials shown on The CW and DC Universe. She was always so bright and cheerful there (with a gorgeous smile), so it was hard to recognize her when she was so serious here.
Pretty good acting from Caitlin Bassett when Addison monologued about telling someone her son had died on a mission. I was lukewarm on her in the role at first, but she's pretty talented when given meaty material.
Don't forget that the project was established to view the past and, as Asimov and others famously pointed out, the past begins one millisecond ago so the ability to observe the past is, fundamentally, the ability to observe the present.
I'm not sure that works in this context, though, since I always thought they could only monitor a time and place where a Leaper was present, using him as their anchor and "widening the field" around him. But I suppose if the means to monitor events in the past existed, it's possible that it could be refined to the point where you don't need a Leaper to lock onto.
Still, I'm not crazy about conspiracy stories, and one thing that annoys me about serial storytelling is that it's led to a profound overuse of conspiracy stories, since serial shows require ongoing mysteries and surprise twists that all tie into a single overall plot, and there aren't many other kinds of story that allow that. Every single time I see a character say "Trust no one," I want the person they're addressing to reply, "Oh yeah? Then why should I trust you when you say that?"
