Just watched the new Dr Strange film and this is where the MCU hits the same problem that the comics have had for years. It all becomes so reliant on you knowing past plots, lore and backstory that it starts to become impenetrable to new watchers. I thought it was ok but hell you need to know what happened in all of the main movies, the TV shows and have an even wider knowledge to understand the Illuminati fully.
We also watched Dr Strange in the Multiverse or whatever it's called. It was decent but I do think this whole multiverse avenue they've gone down is just an excuse to change things in silly ways, like (without spoilers) making female versions or different race versions of certain characters. Some of it even seemed like a rip off of Rick & Morty if we're being honest. Watchable nonsense though I suppose.
As @GB72 since, it was lucky we'd watched WandaVision and everything otherwise half of it wouldn't have made a blind bit of sense.
