He messed up Peter’s spell in such a weird way. I mean, he can make everyone forget Peter Parker existed but not cut the connection between Peter and Spiderman? I feel like as well he’s just out of his prime, plus in my opinion I would like to see a magic battle between Dr Doom and Strange. It would make things more effective too if Strange died to show just how powerful Dr Doom is in just the magic realm. Finally, I feel like he’s gone downhill ever since Multiverse of Madness.
I think Multiverse of Madness was a bad film because while some wanted to make a Doctor Strange movie, others wanted to focus on America Chavez and Wanda. So it lead to a narrative tug of war that ended up hurting all three characters. Also I don’t think it’s accurate to say he’s gone down hill since then because he hasn’t been seen since. I agree with the Dr Doom idea, but Strange has to stay alive long enough to properly introduce Clea.
