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...
