I remember when Dr Strange 1 first came out I thought it was alright (it had some crazy ideas, but presented them in your standard MCU way, plus it had some annoying bathos). After Stage 4 though I've really come to appreciate it more. It organically sets up the Multiverse, it manages to stand on its own while also setting up future, using a few powers in a clever way instead of using many powers in stupid ways, doesn't shit over or what came before it...
