I liked this episode a lot too. I can understand people thinking that it was slower than the first two episodes since it takes place in one location and the TVA is completely absent, but the planet was really interesting. It felt really unique compared to other settings in the series. The entire series reminds of Doctor Who, not just the time travel, but the theme of taking place in these completely different environments in different episodes.
The reveal that the TVA agents are all actually Variants is a massive one that flips a lot of things about the plot on its head. I think most people were suspecting that TVA sounded pretty sinister, but the fact that they're apparently lying to their agents about who they really are basically confirms that there is a lot more going on that isn't right. It's obvious this is setting up some big things that will affect the plot soon.
I wasn't sure how the whole Loki/Sylvie interactions would play out, if they would be enemies the whole time, work together, or dip back and forth. That made seeing their scenes together really interesting to me, and it felt very deserved when they decided to really start to team up since it didn't happen so easily.
I don't know how Loki reversed an entire building falling over though. Due to the nature of Loki's and Sylvie's powers I was spending a lot of time wondering if it would turn out that a large majority of what was happening was secretly an illusion. I'd be pretty disappointed if that was the case though. Maybe he pocketed one of the dozens of Time Stones laying around the TVA...
