I agree, the first 3 episodes (well pretty much all of them) throw SO much information at you, and very quickly. It slows down a bit near the end, much like CA&WS. I believe both that series and LOKI were more written as a movie in the way the pacing is set and overall storytelling, but then broken down into compact episodes.
The events that happened in CA&WS and even WV seem minor and obsolete after the finale of Season 1 of LOKI; you almost HAVE TO watch this series in order to really understand the multiverse and how it occurs. LOKI writers did a very good job setting up and making it pretty easy to understand "time travel" when it can be a very hard concept to explain.
That said, I have so many questions! In what timeline is Loki in at the end? What is the "original" Mobius up to on the "true" timeline? What it Sylvie going to do now?
