I'm cool with 1-3, but would prefer all 4 phases personally. Maybe give it a few weeks, I'd imagine most of us are hardcore enough to have seen it already or in that time.
Also, on a re-watch of Wandavision...the detail in Ep3 of making the set an amalgam of 70s tv shows is brilliant...the Brady Bunch staircase...the Partridge Family colored windows...just amazing.
