Cons:
I just... for one thing, I thought the wedding was going to be where Shit Went Down, and instead it was where People Handed Each Other Weapons and Then Went Home. Just kind of a momentum killer, to be honest. Drugging the wedding cake is certainly audacious, but it's also silly. And I kept thinking that if going to the wedding was just about distributing stuff, why on earth did June and Moira even risk going? Everyone else is supposed to be there. No risk of Serena or Nick or anybody else recognizing them. It felt silly that they'd be there at all.
Serena has this big moment where she learns that her new husband is "just like all the others" and is not a good man, since he brings a Handmaid into their home together. Honestly, the idea that Serena would be surprised by this, that she would have bought into her own delusions enough to believe that this would be a different kind of marriage, didn't really bother me. But the way she reacted? Like, Serena, are you stupid? Just play dumb, lay low, get Noah out of there safely! Now you're on the run with no supplies and no recourse. I just wish she'd played it more clever. Like, nodded and smiled and asked that for their wedding night, it just be the two of them... then in the light of day find a way to get Noah away and figure out a plan. It just seemed silly for her to freak out and burn that bridge with no thought to strategy at all.
