Khürt, I've done that same thing with HBO subscriptions in the past. Subscribe for a month and catch up a season or two of everything at once and then cancel. I find I don't do it as frequently with Netflix because they don't play the same game and there's almost always something new to watch.

I did go out of my way to wait for The Mandalorian to be out completely before I started watching.

I remember several years ago waiting for Breaking Bad to start its final season before I started watching. I timed it roughly so that I would be able to watch the finale day and date of its release to finish off the series.
