Series often talk about big changes but usually only do a soft reboot a la The 37s on Voyager. But this really has been presented as a huge change, so big that the new season is effectively a new series (albeit one with baggage, aka backstory.) If they spend half a dozen episodes going back to something like the first season status quo, the series will be thematically dead. If they do something new, will it be good? Watching to see.
