I didn't think this episode was any worse (or better) than your average Fringe episode.
There's a few references I'm confused about. Maybe they have to do with the new timelines created in both universes without Peter:
1) Fauxlivia mentions the alternate Colonel Broyles several times, but we don't see him. This version of Broyles died when he helped during Olivia's escape attempt, so that must have not happened anymore. Otherwise Fauxlivia might be purposefully not telling them what happened to Broyles.
2) Our Olivia says she killed her step father. According to this Fringe wiki article, she only wounded him, so again the events must have changed. Maybe she doesn't meet Peter as a kid, which changes what she does to her step father?
