fantastic episode, the first 10 minutes felt like Final Destination and a bit tropey but then it turns up up to 11. Dr. Strange is probably my least favorite MCU character but man, him spending CENTURIES eating primordial creatures is fucking insanely crazy and cool. Such a great ending too.
One nice little bit of foreshadowing, The Watcher mentions he could warn Dr. Strange but its better to lose one reality than many. I guess thats a hint of the buildup towards Kang the MCU is slowly heading down, where Strange and/or Kang or multiple people cause the events that do in fact start breaking down many/all realities.
