The ep was worthwhile just for the Astrid/Walter interaction. Nice to see Astrid having more to do. Nice to see Walter actually thinks of her as more than a background lab assitant. Nice to see Walter realize his actions have consequences, etc. Great performances from the both of them.
I agree. The scenes between these two were wonderful and sweet--a real breath of fresh air. But the rest of the episode was average at best. I wish they would focus more on the characters and less on the recycled X-Files plot-of-the-week.
