Okay, Ive always been a bit lukewarm around post credit scenes, but I feel like MoM was the first time a post credit scene actually was detrimental to my enjoyment of the movie.
the last shot of the main movie is this fantastic Rami-esque shot of Dr strange screaming in pain as his third eye opens, its shocking and is a huge "oh shit" moment as the movie has already told us that this is a sign of corruption from using dark magic, it opens so many possibilities for Strange's character moving forward.
Then we have the mid-credit scene and..... Dr Strange is fine, he bumps into Clea for what is a prime example of a
"its me, Blorko" scene and then shows off his third eye like its an edgy tattoo. Suddenly all the tension from that final shot is just... gone
