We’re trying to rewatch Invasion now that it’s concluded (or cancelled). First season is heavy going, lots of parallel plots that only slowly intertwine if at all, and not necessarily so much happening in every episode.
Next will be a For all mankind rewatch to be fully prepped for the upcoming season 5. Let’s see if we can time it so we can binge the new episodes without a week’s wait in between…
If memory serves it started great with season 1, got gradually worse through early season 4, made a shocking comeback in terms of quality for the rest of the season, and then took a nose-dive with season 5. I’m curious how that ends up matching up with your viewing.
This is my memory as well, except not so gradually after S1.
