This has been my favourite Supernatural episode in a long while. A lot of that probably has to do with Misha Collins's acting and the return of the angels and demons. I know some people feel that the whole angel/demon story arc has been played out but personally they're one of my favourite things about the show.

Yeah, that's what I thought as well. I was just waiting for Sam and Dean to run into Charlie only to discover that it was a leviathan who had shape shifted into her.

I really wasn't expecting much from this episode, the promos just made it look a bit tacky but I wound up really enjoying it. It was nice to see Felicia Day, though I did think her geekiness was a little overplayed, she would have been better if it was a little more subtle but that's a minor thing.

Aw Dean, maybe if he got a hug every couple of episodes he'd be a much happier chap. I'm also guessing the angstiness of the show would drop considerably :p

Dean kindof came across as a bit of a dick at the end of this episode I felt. He had a similar overreaction when they found out Cas was working with Crowley at the end of season six, and neither of these situations sat well with me. His reactions just seemed unnecessarily harsh and in both cases he failed to recognise…

I'm pretty sure he's training to be the world's second Analrapist

This episode was pretty mediocre I felt, maybe if it had been placed elsewhere in the series but it just didn't compare to last week's episode. I'm finding it quite odd that they keep giving us big, important, emotional episodes and then following up immediately with standalone episodes that lack any key plot…

I thought this episode was one of the best the season has had, not just because Cas returned. Sam's inevitable breakdown has been looming over us for a while now and I think it was handled well overall. The haunted patient subplot wasn't the best but it was necessary to show us just how badly Sam had lost it.

Hmm. I reckon the grading this week was a little harsh but I've got to agree with some of it. Firstly, curing cancer. Really? Really!? The writers better have something clever up their sleeves to deal with this, if it turns out the leviathans are secretly out to help the humans I'm going to have a hard time believing…

Lucifer was by far the best thing about the episode. I liked that he was helping Sam out and just tagging along with him instead of outright tormenting him. I think in the long run that'll set us up for an interesting relationship between the two of them; we know Sam's more likely to give into temptation, his reliance…

Ted and Robin?! Mother of God, not again! How many times can they re-hash this before we all go crazy? I hope in the next episode she makes him see sense, Imma take this as a moment of confusion and desperation on Ted's part because seriously, if they do this all again or make some twist about how Robin is 'the…

This felt a lot like old supernatural to me, back in season one or season two, in a good way. I've been banging on about plot progression and filler MOTW episodes but I actually enjoyed this. It was so easy to forget about all the crap that's been dumped on Sam and Dean of late, for the first time in a while I wasn't…

Hmm I feel like this episode missed out on a few opportunities. I enjoyed it enough but it didn’t really feel fully fleshed out. The amazons were pretty crappy monsters I thought. What did they really have over the boys aside from their strength? I don’t think they were fully developed as characters; they could have…

Overall I thought it was a pretty fun episode, I would have liked to see a bit more of the 1944 world though, it all seemed a bit too easy.
I've got to agree about the cold open. Was there really any need for that? Surely if they needed filler they could've spent more time in the house or killed off some poor bastard…

Think this is going to be TL;DR comment but I have a lot to say about this episode.
 
I enjoyed the parts of this episode that dealt with Dean/ Frank/ Bobby angst but
the monster of the week stuff dragged. When I started watching it and we got our opening clip of: 'Oh no! This character we have never seen before is in…

I noticed the time lapsing too, I'm really hoping it's significant. If it turns out to just be a symptom of Dean's grief I'll be disappointed, there's potential for something there.
